Opal from Nevada

An old and beautiful opal specimen from the Virgin Valley district in Nevada. In the collection of the Yale Peabody Museum, New Haven, Connecticut.

Opal 4.DA.10 4: OXIDEN (Hydroxide, V [5,6] Vanadate, Arsenite, Antimonite, Wismuthite, Sulfite, Selenite, Tellurite, Iodate) D: Metall: Sauerstoff = 1: 2 und ähnliches A: Mit kleinen Kationen: Silica Familie

Opal Butte crystal with contra luz color with spectacular visual effect. It looks like an underwater view of the ocean floor as light shines through it. There's a surreal quality about the gemstone that looks like a pocket-sized aquarium.
