Doing a Graduate Gemologist Course with GIA

Graduate Gemologists Course with GIA
First of all if you don’t already know Gemology is the science of natural and artificial gems and gemstones, and is a popular course of study for people who wish to go into the gem or jewelry business.
Let’s start with a little background first, well the Gemological Institute of America or GIA as most people refer to it. Established in 1931, GIA is the world’s foremost authority on diamonds, colored stones, and pearls. A public benefit, non-profit institute, GIA is the leading source of knowledge, standards, and education in gems and jewelry.

About Graduate Gemology Course 

The Graduate Gemologist course with GIA or more specifically, the GIA Graduate Gemologist program gives you extensive knowledge of diamonds and colored stones/gemstones you need to succeed anywhere in the world within the jewelry industry. You’ll gain both technical knowledge and utilizable skills to evaluate gemstones by the 4Cs (color, clarity, cut, and carat weight), the International Diamond Grading System™, and the Colored Stone Grading System.
The course covers knowledge on various subjects like, Diamonds and Diamond Grading (Judge and grade diamonds by the 4Cs and color), Colored stones and colored stone grading (Learn the characteristics of colored stones, with a focus on ruby, sapphire, and emerald), Gem Identification (Identify more than 60 species of gemstones, distinguish natural gems from synthetics, and detect gem treatments), Equipment and Instrumentation (Learn diamond identification and grading skills GIA graders use), Treatment, Synthetics and Imitations (Identify diamonds that have been treated or are imitations), Markets and Supply Chains (Understand how market factors and the supply chain affect value) .In Finer detail this is what you can expect to learn and be able to do once you are Graduated Gemologist. You will develop hands-on experience with the GIA International Diamond Grading System™ and the 4Cs (color, clarity, cut, and carat weight) and appreciate how they affect diamond value, Grade diamonds in the D-to-Z color range consistently and accurately, Use gemological equipment and procedures to identify and grade hundreds of gemstones, Identify gemstone characteristics, simulants, and treatments, and anticipate when advanced testing is required, Use technical knowledge for effective sales and excellent service, Discover how gemstones go from formation to the retail counter

Where? How? Why?

Where and how you choose to do your studies is up to you and your circumstances. It’s fairly flexible as you will see, you can study on campus or on a distance (E-learning) program, which consists of 5 eLearning courses and 3 lab classes. For example Carlsbad in California, USA is good if you come from a generational gemstone background like your family business. New York, USA has the best course in Diamonds or GD (Graduate Diamonds), Belgium and Mumbai, India is also very good for the GD course. Bangkok is good for GG (Graduate Gemologist) and Graduate Colored Stones.

Best  Course to do
In our opinion the G G (Graduate Gemologist) is the best course to do as this gives you a wide spectrum of skills for all precious gemstones and semi-precious gemstones. There are some great career paths that these qualifications can lead to. They will steer you in the direction of careers like Appraiser, Auction House Jewelry Specialist, Buyer, Estate Jewelry Dealer, Instructor, Jewelry Business Owner, Lab and Research Professional, Retail Sales and Wholesaler - 
The industry connections that you will make at the GIA are very important and useful to lead you in the right direction, meet the right people etc. For students who in the future would like to work in the USA or export to the USA it is imperative that you do the course in the country so that you can learn and understand the local market and business ethic etc.

 GIA in Carlsbad, California, USA
From personal experience the GIA Carlsbad Campus in California is a very beautiful place to do your studies. The region has many strawberry farms around , it has got a great nightlife with lots of modern & retro style nightclubs. There are also a good variety of quality restaurants as well as all the top franchises and eateries. Another big point is the BEACH! With many Sunday- brunch type places around to wind down the weekend and get some sun. However if you are in Asia and don’t plan a trip to study in America then you should think carefully about the cost of this qualification as it will set you back around $20 000 US.

Don’t despair just yet though here are some alternatives. Thailand is one of the world’s most important gem producing countries and a lot of people come to Bangkok to study Gemology on many different levels and specialized courses etc. The Gem and Jewelry Institute of Thailand is one of the world’s best places to study to become a gemologist. The organization offers an FGA Gemologist Diploma Program, and an HRD: Certified Diamond Grader Diploma Program, as well as several jewelry design courses. The courses are held in English and are accredited through either the Gemology Association of Great Britain or the Antwerp Diamond High Council in Holland. Expect a diploma here to set you back +- $5’500.This does not include accommodation.
 The Asian Institute of Gemological Studies offers a number of gemology courses, beginning with once-off courses for beginners who are interested in the basics. The Introduction to Gemology is a 5 day course that will get you started on your way, if you want to go all the way, they do have a 6 month Accredited Gemologist Diploma and this is the one most people take and our recommendation. This course is a little more expensive and will cost +-$9’100 for the six month course. This does not include accommodation either.

The GIA (Gemological Institute of America) in Bangkok you can start off with a gem identification class, or a jewelry design class. You can also do the Graduate Gemologists Course with GIA in the heart of Bangkok. If you’re keen on distance learning, they also offer this with an Accelerated Gemology Diploma, Accelerated Diamonds Diploma or an Accelerated Colored Stones Diploma. With fees for a Graduate Gemologist Diploma currently at +- $13’000 so make sure you really want to be a certified gemologist before signing up here.

So to conclude there are a variety of options available to study Graduate Gemology abroad (Carlsbad, USA) and in Bangkok through the GIA (Gemological Institute of America), The Gem and Jewelry Institute of Thailand and The Asian Institute of Gemological Studies to name a few.
Happy Studies

Getting to know investment in the big 3 Colored gemstones: Ruby, Sapphire And Emerald.

This article is for the general public. We at Navneet Gems & Minerals know that everyone is aware of the big 3 Colored Gemstones: Emerald, Ruby and Sapphire. In this article we'll discuss whether you should invest in these three gemstones, all the information you may need.

We have been reading many articles about Investment in the big 3 gemstones and after reading so many promotional articles about Invest Invest Invest, in Gemstones. We created this article.

Are coloured gemstones investment for you?

If you are in the industry, then definitely yes. Not just can you sell these at retail prices in the Jewellery shows, but also display the stones in retail stores around the world.

If you are not in the industry, but have plenty of money to invest in various properties, then read on about how you can invest in these Gemstones.

If you are not in the industry, but don't have enough spare money, then this Investment option is not for you. You might be looking for save havens like Diamonds, Gold.

The Big 3 Colored Gemstones


These three are the most sold Gemstone, whether it be loose or built in Jewellery. However, the question is should you invest? First let's understand the prices of "Investment quality" in the three SER precious gemstones.

Assumption: All cut / quality (Best clarity) / color is of the best standards. Color of ruby Pigeoon Blood red. Emerald Columbian sea green. And Sapphire being Royal Blue. (These are all the best colors in their field)

1 carat:
Ruby @$4,000 per carat
Sapphire @$1,500 per carat
Emerald @$3,000 per carat

Clearly these 1 carat stones are not the best investment because of the low $ value, anyone can afford these stones, thus not an investment. Lets give it a number, maybe in a country with artificially 1,000 people with equivalent GDP per capita as USA (which is $53,000), I am assuming according to our research maybe 700 people out of the1,000 people can invest in any of these gemstones. This gives us a score of 70%. Keep this number in mind, it will be used in the upcoming conversation.

5 carat:
Ruby @$20,000 per carat
Sapphire @$8,000 per carat
Emerald @$14,000 per carat

Now these numbers might not ring a bell, but when you calculate the total investment for the above prices per carat for 5 carat, the total value will be:

Ruby @$100,000
Sapphire @$40,000
Emerald @$70,000

This is worth understanding, that Investment in Gemstones need to be understood. With the same GDP per capita of $53,000, maybe 15% of the people can invest in any one of these Gemstones which have a minimum value of $40,000. So that is the number you've got to remember. 15%.

Conclusion: The point of taking from this article is Investment in Coloured Gemstones for actual people is NOT if you buy a expensive stone of $10,000. The value of these gemstones will never increase as much in the long term as if a gemstone is a nice high end 10 carat and more. So if you are having really good money, understanding the graph below of rarity of higher carat weight pieces, then Colored gemstones are really the right investment.

If you need to understand Emerald quality, we did create a Quality chart here for Emeralds, hope it helps understand what an investment grade Emerald is.

Emerald quality chart - World's first of a kind

Being a Graduate Gemologist (GG), our Marketing Manager, Navneet Agarwal, put's all his experience together with the 6 month course in Carlsbad, California he gained, into the world's first Emerald quality color chart. "Grading coloured gemstones with standards is a big problem in this industry and the industry needs standards" says Navneet during his conversation with one of the writers.

For this reason he has created this very important stone's color chart. Hope you like it! We wanted to share it with the world, so when you ask your customer for "quality" you have some type of standards to look at instead of using un-educated terms like "included quality" because Emeralds are always included (99% of them).

A "GG" from the 2014 batch, he graduated from the Carlsbad Campus in California, USA.

The certificate which took him 6 months of hard training conditions

Manufacturer of White topaz: The lower end inexpensive diamond alternative?

In this short article about manufacturer of white topaz like us, we'll explain the diamonds' intrinsic value, we will discuss about the importance of hardness in gemstones, and lastly about us being one of the most important "manufacturer of wholesale white topaz" from Bangkok, Thailand.

People in the coloured gemstones business don't have a "thing" for diamonds. We really don't, neither do I, neither do the people working in our company. The reason is we see so many coloured gemstones around us everyday, we never get fascinated by plain white. We see it as a colourless stone, sorry for fella's who love Diamonds, but we are not a big fan.

One of the reasons is also the high marketed price of these Diamonds. And why not, when we deal with stones like White topaz (Hardness of 7 on Mohs scale), which are super inexpensive, how are we going to love Diamonds? In our minds, this fact that 1 carat Diamonds may cost upto $15,000 for the buyer, where as a 1 carat White topaz (Giving the same look) may cost just $1.5. We totally are in love with Topaz.

The hardness

When we see Diamond's marketed as "forever" and "the most expensive" gemstone, we'd see that Topaz is not a soft stone at all. Because of the hardness of White topaz, we get really nice polish and facetting on this beautiful colourless stone, which comes dirty in nature (Unclean), and human hands saw the unclean part of the rough out to get to the public the beautiful clean topaz we see in the market.

Interestingly enough, white topaz is a more consumed gemstone in terms of carats compared to Diamonds. The reason? The price range. Small sized White topaz pieces may cost you $0.30/piece. Yes, PER PIECE! Compared to the diamonds of the same size, lets say at least x100. With this big price difference, what are you going to choose?

Your ultimate complete source for Topaz

Now, if you have reached this blogpost and are now wishing that you would have a reliable source of white topaz stones. Well, here we are. Navneet Gems and Minerals specialise in white topaz wholesale. We are your manufacturer of white topaz, from Bangkok. We have a cutting factory located in China for the small sized white topaz. So if you need those "small size white topaz china made" then well look no further.

Our First Advert Navneet made back in 2006

Not only are we carrying a large variety of white topaz in the smaller mile sizes like 1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.75 mm, 2 mm and so on, we also do a lot of larger sizes of white topaz.

Since we are a White topaz manufacturer, we have rough from all sizes graded, between 1-2 grams, 2-3 grams, 3-5 grams, 5-9 grams, 9-15 grams and then the largest sizes 15 grams and above. Let me explain the type of orders we get for wholesale white topaz from our customers regularly: Most things that are not available with whole sellers in white topaz in Bangkok, like Cushion 12 mm 1000 pieces. That is a very popular shape that we are getting regular orders of white topaz in. The reason that this shape people don't keep stock. Sometimes we get inquired about Briolettes, Cabochons and Fancy millennium cut. 

One of our factory in jaipur manufacturers Wholesale White topaz stones in loose form at quantities of 2,000 pieces per day of preforms. Most of the cutting of our stones take place in our headquarter factory, in Bangkok, where cutting and polish is superior to any place in the world, surpassing China. Our cutting factory in Bangkok include a team of 37 cutters and polishers who are regularly working under our guidance.

For inquiries about white topaz in bulk or getting in touch with us for any sort of collaboration, email

What is topaz used for?

People who purchase white topaz from us at wholesale, not just buy it and start selling. (Do check out the different colors of topaz in the start of the article). These are the following purposes:
  • Coating White topaz into different colors from Azotic or Chinese companies
  • Using white topaz to be used a replacement of diamonds, or just simply the use of white coloured stones
  • White topaz can be coloured in Sky blue topaz, by the Irradiation process. Some of our customers get it done in Germany (German treatments of sky blue topaz are the best but expensive) and some get it done with companies in Bangkok. Some of the colors that can be made are here.
  • Some give the white topaz to us for Irradiation as we have a pact with some of the best companies in Bangkok for colouring into sky blue.
  • Treatment into Swiss blue topaz, Baby Swiss blue topaz, London blue topaz.
Swiss Blue Topaz

    London Blue Topaz
  • Investment, the big 200-300 carat pieces are ordered for this purpose yes!
  • Carved in white topaz budha, or white topaz jesus christ cross? Multi purposed.
You may also see here how Mystic topaz is made from White topaz, it is a video shot by us at Navneet Gems.

Don't forget to share this article and comment about: Who is going to buy diamonds at such prices? With the big price difference what are you going to choose between White topaz and White diamonds?

Diamond prices and why this is the time to invest in Diamonds

We are no special expterise when it comes to Diamond prices, but the Rapaport prices are definitely falling. We aren't saying but are the media. See some images below.

Now, what are the reasons why the diamond prices have fell?


"Diamonds are forever" and the "Forever mark" - things like these are marketing slogans that have costed De-Beers millions. For those who don't know De-beers is the company behind all the marketing of Diamonds, because they hold a large percentage of Diamond mining. These marketing ways had made people perceive that really Diamonds are a good investment and are the best way to propose to a girl. Because "Diamonds are girls best friend" who hasn't heard these famous slogans? So what is the problem?

These marketing campaigns have turned old, it has been there for years, people needed a change. All the elder generation still believes in these diamonds, but the newer gen, not so much. Now comes the new advert that De Beers has launched.

James Bond 007 Marketing Campaign back in the 20th Century.
The latest marketing campaign that is just recent launched.

Why to Invest in Diamonds now? And which ones?

The huge boom in diamonds have slowed and now the prices have adjusted to its worldwide levels. The chinese market and the russian market slowdown has also been the cause of this. So this is the price that were 5-6 years ago. Now it can only go up, with the view of the new upcoming asian markets, we do suggest that this is the right time to invest. Especially in fancy shapes because those are even rarer, the most common shapes are rounds and you can easily find, when you sell it, there is nothing exciting about the shape.

This is the right time to invest in diamonds, and if you are looking for a wholeseller of Diamonds from Bangkok click here. This person is actually someone I met in Bangkok, he has a vast collection of Fancy shapes of Diamonds, that is the reason I suggest to go to this company. He really makes it worth your time and gives a good wholesale deal. On their website it also mentions their stockist.

Thanks for reading, do comment about "what your favourite diamond shape is"? Ours is certainly a Octagon (Asccher).

Giving less importance to origin of Sapphires – The introduction of Nigerian Blue sapphires

  •          For those who are into: Investment in Blue sapphires. 
  •          Wholesale? Going for the look? Nigerian sapphires are the answer to nice quality sapphires for repeatable purchases. 

         For decades Wholesale Blue sapphires from Ceylon have been the most wanted origin of sapphires for reasons of fire and brilliance and color’s hue and saturation and tone. With the introduction of Blue sapphires from Nigeria – I will here talk about why Nigerian blue sapphires are the most important replacement for the famous Ceylon sapphires.

Different colors of Blue sapphires

As I was flying from Hongkong to Bangkok, having exhibited the Hongkong Jewellery Manufacturer’s show 2015 in Wan Chai, I came up with this analysis, during the flight. Ofcourse more corrections were made later as I came to work on Monday.

Some background about Nigerian sapphires: Nigerian sapphires were found in 1990’s, but the commercial production of nice high quality and in quantities really came around in 2014, last year. GIA, however, only wrote an article about these in late 2014. Wholesalers of Sapphires like us, with our network, we found about these only a week later Sapphires came to the local African news. 

This is what we did when we found this out:
  • We stocked about 50,000 carats of Blue sapphires
  • Mainly calibrated sizes for repeat orders
  •  Sizes from 2 mm size rough to 10 mm size rough.   
 Last year when I was at GIA meeting at the JCK Las Vegas show, one of speaker talked about Africa, as the important region to help issues with quality and availability of nice quality precious and semi precious gemstones.
      For investment? Alright, give importance to the origin of the sapphires.

      The origin of the sapphires are a more important investment factor when an investor is planning to spend some money on high end Blue sapphires. Fine, go for Kashmir or Ceylon Blue sapphires. The reason is because these origin stones gain the highest value of all origins due to the rarity and the quality we tend to get from these origins. Kashmir, being in the middle of Pakistan and India, is a difficult place to mine for sapphires, thus being one of the reasons of high prices on these sapphires. Ceylon (Srilanka) is a small island in the south of India, how much natural resources can it give out? In the past few years, Ceylon sapphire sources have dried out.
      Wholesale? Going for the look? Need something more economical without compromising for the look? Go for Nigerian Blue sapphires
      According to our subjective analysis, more than 90% of the Blue sapphires found in the US stores are either kancha (Kanchanaburi, Thailand) or Nigeria sapphires. The reason is, when you are looking for calibrated blue sapphires stones in wholesale, you want to buy repeatable items, only these two origins produce Blue sapphires which can be sold today and bought again tomorrow from wholesalers like us in Bangkok.
      Now, if you really are one of those who like Blue sapphires for their look and believe blue is in trend, (More than 70% of the youth these days perceive looks and buzz as the buying reason of any gemstone jewellery) then really Nigerian sapphires are for you.

     Some Interesting facts that I’d love to share with my readers about this topic:

  •             I don’t say that for every piece of Ceylon blue sapphire you find in the market, you can find a blue sapphire from Nigeria to replace it at a lower price, but you can definitely find a similar piece and sometimes at a better look then a Ceylon. Quality and color of Blue sapphire is explained here:
  •       The new heating processes are producing some very find quality Nigerian sapphires that can literally be mixed in a parcel of Blue sapphires from Ceylon without having anyone realize it.

Should we collect gemstones as collector?

Why not, would be my immediate response. Collecting gemstones can be a very satisfying and fun activity. The gemstones may not provide easy income but they provide a “physic” income to the collector which is incomparable to any such monetary incomes. Buying , possessing and occasionally viewing of your gems will give you feeling that is indescribable. The true motive of collecting gems is the pride you incur with owing some of the finest gems present in the World. Gemstones should be collect for their beauty, rarity and enjoyment they give. And, if in case there value appreciates then surely it is bonus for you. Here, are the three facts about the Gemstones which attracts the collectors towards them:

  • Gemstones are inherently interesting; a person could literally spend his lifetime in knowing various physical and metaphysical properties of different gemstones.
  • Gemstones come in extensive range. There are thousands types of gemstones available. The huge range of gemstones can satisfy the collector’s urge to build a collection.
  • Some gemstones are rare. Rarity and uniqueness of the gemstones attracts collectors.

The obsession for the possession of the Gemstones is not new. The history has witnessed gemstones as a gift and ransoms of kings and queens, the reason for the overthrow of rulers and misdeeds of violence. The most famous gem collectors are George Frederick Kunz, Thomas Edison and J.P. Morgan from left to right

Collect What You LOVE!!
Most Gem Dealers will advise you to collect gemstones those are beautiful and/or rare. But do not get afraid in collecting other varieties of your interest. After all, collecting gemstones is a hobby and you should take pleasure in buying and owing gemstones.
Someone may find pleasure in collecting rainbow colors of one species available with the gemstones like Spinel, Tourmaline, Garnet or Sapphire. While, other may love to collect intense and vivid shades of blue and can build up the collection of all the shades of same colors from gemstones like Blue Spinel, Tanzanite, Sapphire , Kynaite, Blue Topaz etc. There are people who are fascinated to highly sought fine gemstones like Colombian Emeralds, Unheated Rubies or Kashmir Sapphires. To some collecting birthstones or anniversaries gemstones is a hobby. The possibilities are endless these are just few examples.

For beginners, we suggest to collect Amethyst, Agate, Aventurine, Bloodstone, Citrine, Carnelian, Fluorite, Howlite, Rainbow Jasper, Lapis Lazuli, Peridot, Moonstone, Clear Crystal, Rhodonite, Sodalite and our own special Blue Topaz.

Find a Good One!
Navneet Gems and Minerals advise to both the new collectors and advanced collectors to always collect fine quality gemstones. Though, the prices of commercial qualities will attract you at first glance but, fine quality gemstones would have better future selling prospects.
Eye-catchy Color!
Color of the gemstone should be bright, pure and of moderate tone. Colors of metallic minerals such as gold, silver, copper, platinum , pyrite etc are very attractive colors to collect. Colors like intense yellow and intense red are rarer therefore commands higher prices than usual blues, greens and metallics. Remember, these colors are no less desirable either.

Up Size!
Bigger the Better. If you can afford, always buy large-sized stones. As the large-sized stones are rarer than small-sized and are more in demand. Do not buy stones less than 1 carat. Depending on the type of gemstones size matters. A Ruby of 3 carats is considered large and rare. While, Sapphires of 10 carats is considered large and rare.

Rarer the better!
If your budget allows, then collecting the rarest gemstone varieties such as Painite, Musgravite, Benitoite, Jermejevite, Cuprite, Red Beryl, and Pezzottaite etc. can prove a worthy deal.

We, at Navneet Gems and Minerals understand that fine gems historically appreciated over time, but not like real estate. Our experts are 24*7 available to help your customers to do wise shopping with us. I am sure you will find stone of your love from the extensive range of our Precious and Semi-Precious Gemstones.

Unofficial trafficking of rubies rough

All precious stones and medium priced stones (Tanzanite, Tourmaline, Peridot etc.) are unofficially supplied from one country to another country. Burma and Thailand are neighboring countries and big amount of rubies from Mogok and Mong Shu (regions in Burma) are trafficked in Thailand by unofficial ways where cutting, polishing (final production) takes place. Refugees sometimes use unofficial river crossings to get into Thai border. They risk their life to save tax charged on rubies rough.

Here is a chart explaining ruby from mining to selling of finished goods. - Mogok and Mong shu are situated in Myanmar (Burma) and Bangkok and Chataburi are situated in Thailand.
- Mae Sot and Mae Sai are situated in middle on both countries.

It is very difficult to judge by eyes and tell its origin and many smugglers takes advantage of it. They mix Burma rubies and rubies from other origin and sell mix lot unofficially to a buyer.  Few experts know some ways to check the quality and origins.
