Fantastic highly lustrous, dark emerald-colored demantoid garnet on matrix. Demantoid is the green gemstone variety of the mineral andradite, a member of the garnet group of minerals.

A forest-green andradite (v. demantoid) garnet crystal is perfectly placed on one side of this matrix specimen. The crystal measures 19 mm in diameter. This specimen is in excellent condition. The crystal surfaces are high-gloss with a very fine structure. The appealing individual crystal sits exposed on a bright matrix, which makes this specimen a very beautiful and truly impressive sight!
