Sharp, lustrous, battleship-gray, cuboctahedral galena crystals are richly and aesthetically scattered on all sides of the sculptural matrix consisting mostly of sparkly, brass-yellow pyrite microcrystals on this fine specimen from the Greystones Quarry of Cornwall. The Quarry is a modern operation worked for road metal. Strangely, galena is rare in crystallized specimens from Cornwall. Ex. Wesley Stark Collection.
