Classic duck-egg blue glossy botryoidal Smithsonite from the world famous Kelly mine in Socorro County, New Mexico, USA. This is certainly an iconic form of Smithsonite and as a cabinet-sized display specimen this is a really fine example, showing fantastic undulating surfaces with a silky surface texture and rich colour. The size of the botryoids varies from very small on the raised surfaces where a thin layer of turquoise-blue Aurichalcite appears to have disrupted the outer layer of growth, to slightly larger within the cavities. It comes from the superb collection of Martin Kershaw in the UK, who started collecting during the 1960s.

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.
