Natural Blue Chalcedony Rough Stone | No.176

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

Chalcedony is quartz grown too finely to show any grain, so it takes a waxy lustre rather than a glassy one and light travels a few millimetres into the surface before it stops. The pale blue reads deeper wherever the stone is thickest and washes out over thin edges, which is why the form changes as you turn it against a window.

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.
