Afghanistan is quite capable of producing some of the world's finest, most intensely colored Tourmalines. Though these are often overshadowing by cuprian stones from Mozambique, the bright sea-green colors of these Afghani stones is quite unique. This is an exceptional example, of larger size and very intense color. 

Tourmaline is a six-member ring cyclosilicate having a trigonal crystal system. It occurs as long, slender to thick prismatic and columnar crystals that are usually triangular in cross-section, often with curved striated faces. 

The rarest and most expensive tourmaline is the paraiba variety -- a neon-like blue or green that is colored by traces of copper.
