82 - Emerald set in silica stone.

Emerald set in silica stone. Measurements: 17 x 17 x 10 cm. A natural mineral specimen notable for the presence of emerald crystals embedded in a dark, siliceous rock matrix. The veins and prismatic formations, with their intense emerald green color, contrast sharply with the rough, matte texture of the host rock. Although these emeralds lack the purity or transparency required to be cut as gemstones for fine jewelry, their great visual appeal and shape give them significant value in the mineral collecting and interior design markets.
