Tourmaline

Perhaps the most diverse gemstone available, tourmaline possesses a dazzling array of colors. Moreover, there are bi-colored and tricolored tourmalines where two or more colors appear side by side in the same gemstone.

An October birthstone, tourmaline is also the chosen gift for the 8th wedding anniversary. 

The name tourmaline means multi-colored, a modest description of the variety that exists in this mineral family, which includes dark green chrome tourmaline, deep blue to blue green indicolite, pink to deep red rubelite and watermelon tourmaline. Color determines price, with lively, mid-colored gems valuable.
