Description

Numerous highly lustrous crystals set on dark matrix, a sprakling pyrite crystal at the lower base gives even more contrast to the piece. Very hard to capture this intense green color - but you can be sure: in person this is the best green you know from Colombia. All crystals are sharp and lustrous, just hard to see that the whole green area on the photo consists of small crystals. Much better in person!
