Not all tourmaline gemstones have the same value. Some varieties are especially rare and desirable, while others are almost as inexpensive as quartz. Interposed between these are a range of fascinating colors that represent some of the best value gemstones. Here's a quick guide to tourmaline gemstone value.

Bi-Color Tourmaline

Undoubtedly, the most rare and costly type of tourmaline is the highly sought-after Paraiba tourmaline, characterized by its electric blue-green hue. Initially unearthed in the Brazilian state of Paraiba in 1989, this variety, colored by copper and manganese, caused a significant stir in the market. The overwhelming demand and scarce supply led to the depletion of the original Brazilian mine. However, in 2001, similar copper-infused blue-green tourmaline was discovered in Nigeria, followed by another find in Mozambique in 2005. Despite these additional sources, the supply remains extremely limited, resulting in exceptionally high prices.

Paraiba Tourmaline

Another valuable tourmaline variety 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 1960s and is quite a rare material. Generally it can only be found in small sizes, which are usually of high quality. The color is typically a pure forest green with slightly yellowish to bluish secondary hues.

Several other colors of tourmaline are especially valued when their colors are particularly intense. They include the ruby-red rubellite and the hard to find blue indicolite.

At the opposite end of the spectrum, the black tourmaline known as schorl is the most common and least expensive of all the tourmaline varieties. Since it shares the same excellent gemstone characteristics with the other varieties of tourmaline, it is a superb value gemstone.

Other common tourmaline colors that are not particularly expensive include yellow-green, brown and orange. Specimens with a particularly intense color and good clarity will tend to be priced higher. Pink tourmaline usually commands a high price, 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.
