Leopard Skin Jasper is a visually striking, orbicular variety of chalcedony characterized by multi-colored, leopard-like spots of red, brown, tan, and black. It is typically found as a secondary infilling in rhyolite or volcanic rocks, making it a highly popular material for cabochons and decorative carvings due to its intricate, patterned surface when polished.
