Item Description

Six olmiite crystals are aesthetically clustered on a rich carpet of sparkly, gemmy calcite crystals on the large sculptural hefty layered ore matrix. The blocky to rounded lustrous and translucent olmiites, to 1.6 cm, are composed of a myriad of intergrown orthorhombic crystals with fine light cinnamon color. The crystals glow, when backlit. Showy and excellent large combination material from finds about 10 years ago.
