The silvery, wood-grain banding seen in the finest pieces comes from layers of pyrolusite running through the stone. It takes a quality polish that highlights the contrast between the jet-black base and the bright metallic banding, working into dramatic designer-grade cabochons and eye-catching display slabs. Gem-grade material has always been a rare find on the lapidary market.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWHAT MAKES IT SPECIAL\u003c\/strong\u003e\u003cbr\u003eThe \u003cem\u003emetallic plume\u003c\/em\u003e and \u003cstrong\u003ehigh-contrast banding\u003c\/strong\u003e make this a dramatic cab or display piece.
