The Value of Tourmaline Gemstones
Tourmaline has become a very popular jewelry stone due to its amazing range of colors, its very good hardness (7 to 7.5 on the Mohs scale), and its vitreous luster and excellent clarity. While tourmaline does not have an especially high refractive index -- rating between topaz and peridot -- there is no other gemstone which displays such a variety of colors, sometimes even in the same gemstone!
But not all tourmaline have the same value in the market. Some varieties are especially rare and valuable, while others are nearly as inexpensive as quartz. In between are a range of fascinating colors that represent some of the best values in the gemstone world. Here's a quick guide to tourmaline value.
Surely the most rare and expensive tourmaline is the so-called paraiba tourmaline, an electric blue-green variety that was first discovered in the Brazilian state of Paraiba in 1989. Colored by copper and manganese, this new tourmaline caused a sensation in the market.
Another valuable tourmaline is chrome tourmaline. Colored by chromium and vanadium, this rare tourmaline displays a rich, intense green that rivals the very finest emerald and tsavorite garnet. Chrome tourmaline was first mined in Tanzania in the 1960's and is not often available.
At the opposite end of the spectrum, the black tourmaline known as schorl is the most common and least expensive of all the tourmalines. Because it shares the same excellent gemstone characteristics with the other varieties of tourmaline, it is a superb value.
Other common tourmaline colors which are not particularly expensive include yellow-green, brown and orange. Pink tourmaline usually commands a premium, especially the hot pink. The same is true for interesting bi-color and tri-color pieces, especially the very popular watermelon tourmaline which combines red, green and sometimes white bands in the same stone. But it is fair to say that all the tourmaline varieties offer outstanding gemstone value.
