Andradite (Var: Demantoid)
Ghazni (Gazni) Province, Afghanistan
Cabinet, 13.0 x 8.7 x 3.4 cm
This hand-sized specimen hosts dozens of small, sharp, highly lustrous, gemmy, bright green modified dodecahedral crystals of Andradite (var. "Demantoid") on schist matrix. Please note that these crystals show a color change from a "mint green" color to a very rich "lime green" hue in different lighting. Under halogen lights, the crystals appear more pastel, but under mercury bulbs, the color is very intense.
