Item Description

An ULTRA RARE and UNIQUE combination specimen from the famous Tri-State District of Missouri, Oklahoma and Kansas. This showy, OLD-TIMER features glassy, jet-black bitumen (a "solid oil" or hydrocarbon material) scattered amongst a rich covering of lustrous, metallic-gray galena cubes and sphalerite crystals on a vuggy, two-sided matrix of silicified limestone coating with tiny, contrasting, colorless calcite rhombs. The back even features a couple of quartz needles, as a highlight! A VERY UNUSUAL and RARE, OLD-TIME combo piece from this historic district and the George Feist Collection.
