STF106c Stefoinite Cabochon

Stefoinite is a rare brecciated jasper from Wyoming, most likely Sweetwater County, discovered originally by Rudy Stefoin. Material is limited as the exact location is no longer known, and collecting last occurred in the 1970s. Typically, it shows tan jasper with brecciated patterns filled with translucent black, white, or blue chalcedony. This polished Stefoinite cabochon features varying shades of tan with dark brown and black within the brecciations, and small spots of translucent blue-grey agate. 29mm x 37mm Designer Cabochons: The Gem Shop, Inc. produces free form designer cabochons for the custom metal smith, hobbyist, and collector.
