Description

Fre-standing and highly lustrous Prase crystals in dark green color set on matrix. The crystals show excellent luster, they consist of countless, razor sharp termianted tiny steps. The matrix is partly covered with tiny red-brown Andradite crystals - this is really a very fine contrast! The two largest Prase crystals are formed like a "V", the whole arrangement looks very aesthetic.
