An Introduction To Loose Tanzanite Gemstones –

“Tanzanite” which comes under the “Zeolite” category, is a purple-blue gemstone and that has the optical phenomenon of  Pleochroism which means It shows a different appearance of color from different sides and different levels of lights give it a striking look. The blue color of this stone is so fascinating that it replaced Blue Sapphire in some jewelry designs. As mentioned above that it shares the pleochroism property is why cutting of the stone plays a vital role in the market value of the Tanzanite, and the real challenge is to cut the stone in a way that shows the most pleasant color through the crown part and another challenge is to make sure that it is cut as minimally as possible because carat size matters a lot in this stone.  When we talk about treatment, all Tanzanite Gemstones are normally heated, which is acceptable and understood in the market. Our own factories are located in Thailand & India, producing High Quality and Medium Quality Wholesale Tanzanite Cut and Wholesale Tanzanite Cabochons. We specialize in both cut and cabochons.


The Chemical Formula of Tanzanite is Ca2Al2(SiO4)3(OH) ( Calcium aluminum silicate ) and comes with an orthorhombic crystal structure and 6.5 to 7 hardness on the MOHS scale and has 3.35 density. The luster and transparency level is also good in Tanzanite Gemstone which comes with a 1.691 to 1.700 refractive index. It comes with a purple hue with the primary blue color.

Who named it “Tanzanite”? How was the real value of this stone recognized? Who discovered the mines of this stone?

In 1967, a Masai Tribesman found the vivid blue and transparent crystals in North Tanzania (East Africa) and later on he informed his local people there and claimed and registered new mines there. It was mistaken as Sapphire in the beginning because of the same intense blue color. In the next few months, this news spread to nearby areas and more than a hundred claims were registered in the area.

Soon this news aired in gemological circles and gemologist started to study the mineral, chemical structure, and composition of this stone and they found that it was a combination of Al, Calcium, and Sio2 with a hardness of 6.5-7 on the MOHS scale. The interesting thing is that the demand graph for this stone increased rapidly. It was Tiffany and Co. who took the first step to promote this stone in the market by the name of Tanzanite because it was discovered in Tanzania and they marketed this stone as a replacement of Blue Sapphire and as “Africa’s Mystery”.

Tanzanite is America’s pride, it is the American Dream. But dreams do come true and that’s what’s happening around this country of America, dreams are coming true. Tanzanite is one of the loveliest gemstones in today’s market. Facetted stones are the most commonly bought and thus produced the type of cutting style. With not too much room to play around with the creativity in this highly valued stone, the most common shapes are just Ovals, Rounds, Pears, Octagons, Hearts, Marquises. But Ovals really stand out at the top of the pyramid.

Color and Quality Chart of Tanzanite

Just like other stones, the 4c’s (color, clarity, carat, and cut) play an important role in the price of this stone. The bigger and more vivid blue stones are higher in price. A manufacturer makes a decision based on market price, whether to cut considering the size or face-up color. You can understand the clarity very easily by seeing a normal quality Tanzanite Cabochon and Tanzanite Cut Stone because normally cabochons come in unclear quality in comparison to cut stones. A nice quality tz stone must be cloud-free and crack-free with good transparency and color saturation. Here is the general Color Chart of Tanzanite and you can easily ask the price from us based on your desired color. A gem quality Tanzanite is an intense violet-blue all over the stone with perfect saturation of color. Another price factor is shape and ovals, rounds, cushions, and octagons are much more valued than marquise, trillion, and square.

Tanzanite Demands in Market and Supply –

The price parameters of Tanzanite, are just like Precious Stones and there are different markets for calibrated, big-size, top-quality stones. How calibrated and low-quality Tanzanite came into the market soon now you will understand by reading an interesting story behind Tanzanite. There is an interesting graph between demand & supply, prices & supply of this stone. In the very beginning when Tiffany and Co. started to promote this stone to big jewelry companies as a replacement for Blue Sapphire, supply was available in big quantities but demand was low. Later this stone became very popular and the Tanzanian government took the supply and mines under their control and the supply became low and the low supply raised the prices of available material in the market. By seeing the skyrocketing prices, big companies stopped using this stone in their designs. After 10 years, the Tanzanite story took a new turn when thousands of independent suppliers took over it and low supply became oversupply and both calibrated sizes and big sizes were available in big quantities in the market, so prices came down and later on the Tanzanian government released some strict rules and supply of this stone become limited again and now prices are increasing day by day.

Tanzanite Cabochons

Tanzanite Cabochons are really very famous for their prices. I mean Americans love Tanzanite and since the early 21st century it really took off. But recently since the general quality has started to go down, Tanzanite Cabochons have also like other cabochons become very trendy. Tanzanite cabs are un-replaceable. Nothing can really beat them in terms of Tanzanite’s color and quality. Can you think of a different stone other than Tanzanite which comes in the same quality, color, and properties as Tanzanite? The answer is probably no.

Generally not the most preferred quality of Tanzanite Cabochons, here in the picture. But when it comes to the price point of view, the price is way less in the lots above.

Most of the Tanzanites we have right now are in 2 qualities depending on what price range the customer is looking for. Can you see that the Tanzanite lots usually have Purples and the Blues mixed together? Just try looking for the Tanzanite pieces that look quite purplish and on the other hand the ones that have just a blue tone ONLY to them. We sell Cabochons in calibrated too but are less common due to its small price difference between these and the Facetted Rounds. But due to our huge inventory in Tanzanites, it just becomes easier for the customers to select what they like, according to how much they are willing to spend on each item.

Navneet Gems & Minerals is a leading supplier of Wholesale Tanzanite, and we have grown since the past 5 years incredibly because we source our gemstones straight from Tanzania, the only place where mining for Wholesale Tanzanite takes place.
