September 2016 Newsletter: Tanzanite Prices and Value

 

It is fair to say that Tanzanite, the vivid violet-blue gemstone from East Africa, is one of the great modern success stories in colored stones. Discovered just in 1967 in Tanzania, it was named and promoted by Tiffany & Co., who described it as "the loveliest blue gemstone discovered in over 2,000 years." To this we would add that it is also one of the best values in the world of colored stones.

We say that because a saturated and vivid blue is actually one of the rarest hues in the gem world, nearly as rare as a pure red. Until the discovery of tanzanite, sapphire was really the only gemstone found in a richly saturated blue -- aquamarine and blue zircon were a light to medium blue, while blue spinel tended towards a greyish-blue.

When you compare tanzanite to blue sapphire, you'll find that some top grade tanzanite has color that rivals not only high quality sapphire, but the very finest sapphire you can find, colors that sell for many thousands of dollars per carat. Tanzanite also tends to be exceptionally clean, with many high grade stones loupe clean or almost loupe clean.

If that were not enough, tanzanite can also be found in larger sizes. Blue sapphire is rare and expensive over 2 carats and good quality sapphires over 5 carats are extremely expensive. Tanzanite, by contrast, is quite easy to find in the 4 to 6 carat size, and even gems over 10 carats are not unknown. 

In defense of sapphire, it is certainly a harder and rarer gem, and market prices reflect this. But while sapphire is exceptionally hard (9 on the Mohs scale), tanzanite is still hard enough (6.5 to 7) for ring settings, particularly rings which are not worn daily.

In its 45 year history, Tanzanite prices have fluctuated, due to variable supply and inconsistent promotion. But Tanzanite mining and distribution has slowly become more professional and in recent years prices have been stable.

At Bangkok direct prices from AJS Gems you can expect to pay in the range of $400 to $600 a carat for top color Tanzanite in the 4 to 9 carat size. You are unlikely to find lower prices on fine Tanzanite from any source, unless you are buying the rough stone and cutting it yourself. 

Prices for very fine unheated fancy color tanzanites, such as the rare pinks and purples, can easily run 2 to 4 times higher than the blues, particularly for vivid colors in stones over 1 carat.

Ask the Gem Experts

Each month we answer questions from our customers. We welcome your questions and you can submit a question from our contact page.

What is the color called padparadscha? What gems come in this color? Thanks for your help, BL, USA

The term padparadscha refers specifically to the natural pink-orange color of some sapphires. But similar colors can sometimes be found in spinel, tourmaline morganite and malaia garnet. So if you love the delicate pink-orange color, it is possible to find it in other gem varieties.
