Smithsonite

Smithsonite from Kelly Mine, New Mexico, USA

Kelly Mine smithsonite is one of the defining American classics: rounded, grape-like masses of blue to blue-green zinc carbonate with a glow that can look less like a mineral surface than a pool of frozen water. The best pieces are the famous “Kelly blue” specimens—translucent, lustrous botryoidal crusts and spheroids, often with pale internal banding visible along broken edges or natural windows. Fine examples combine color, luster, depth, and undamaged rolling form in a way that makes them instantly recognizable across a room.
