Chrome Dravite Chrome Dravite Chrome Dravite Chrome Dravite

Amazingly rich chrome green Dravite that grades up to a cat's-eye termination. You may recall similar but brown crystals that were found at this mine in quantity over the past couple years. This crystal is new (late 2017) and the only one like it that was available - we can only cross our fingers that more will be found. Undamaged with an incredible color that is slightly more vivid than other Tanzanian green dravites.
