This gemstone is made of a different member of the tourmaline group than most of the gemstones in this collection. It is a vanadium/chrome (most of the time the vanadium dominates) colored Dravite, the species. Dravite has magnesium in it and no lithium, that is in Elbaite, the principle gemstone making tourmaline. The green that is produced has a different visual impact and is both quit desirably and expensive. It is general too dense/dark to be cut effectively in larger stones. This oval 1.21 carats show its color mostly threw its flash. Which is dark by may standards, but it is a great color.
