Chrome Tourmaline is a rare variety of Green Tourmaline that is found only in Kenya, Zambia, Namibia and Tanzania.

The finest Chromes rival the top color of Emerald and offer a more durable stone for jewelry. Chrome Tourmaline's vivid Green color is determined by the presence of Chromium or Vanadium oxides. Chrome Tourmaline was first mined in Tanzania in the 1960's. One of the largest crystal chambers was uncovered by accident in Namibia when an explosives expert shot off excess dynamite. Gem quality Chromes are extremely difficult to locate. Stones over 2.5 Carats are considered very rare in this Gem. A very rare Gem with a great investment potential. Report from established Asian Institute of Gemological Sciences, commonly known as AIGS (Thailand), certified "Natural Chrome Tourmaline"
