Owyhee Natural Blue Opal Faceted Rondelles have a waxy luster, opaque transparency, fair polish, and asymmetrical shape. Their color ranges from a light saturation of slightly greyish denim blue to a creamy white hue with scattered areas of a platinum grey hue for a very soothing group of Blue Opals. The original source of these type of opals is near sacred Native American Grounds in Oregon.
