About the Stone
The concentric banding in agate records successive deposits of silica against the wall of a rock cavity, so a slice cut through the nodule reads as a set of nested lines. Where the drop is cut decides how many bands appear and how tightly they sit. Colours here are natural creams, rust and grey-brown.
- Family
Chalcedony (microcrystalline quartz)
- Hardness
6.5 - 7
- Note
Agate's banding is a record of deposition: silica-rich fluid entered a cavity in volcanic rock and laid down layer after layer of fine-grained chalcedony against the cavity wall, each layer differing slightly in trace content and grain size. No two slices repeat.
