Natural Blue Chalcedony Rough Stone | No.168

A rough stone cut from a single block of blue chalcedony.

This is cryptocrystalline quartz — the crystals are there but far too small to see, which gives blue chalcedony its soft, slightly greasy sheen and its translucency. Held up to a lamp the pale blue-grey lets light through at the edges while the thicker passages stay opaque.

Shaped to sit in a closed hand — the proportions are decided by the grip rather than by any outline, and the finish is worked smooth enough to be handled without catching.
