Description

Fantastic, highly lustrous, dark emerald-green demantoid garnets on matrix. Demantoid is the green gemstone variety of the mineral andradite, a member of the garnet group. On one side of this matrix specimen, four forest-green, highly lustrous andradite (var. demantoid) crystals are perfectly positioned. The reverse side hosts even more crystals, which are significantly larger—three of them grown together span a combined diameter of 3.3 cm. This specimen is in excellent condition. The crystal surfaces exhibit a brilliant luster and fine texture. The well-exposed, sharply formed crystals on the bright matrix create a striking visual contrast, making this a truly beautiful and impressive piece for any collection.
