Quartz coloured by iron

Amethyst, raw cluster

$88

Amethyst is quartz — silicon dioxide — coloured violet by iron sitting where silicon should be, plus a few million years of background radiation. It is a 7 on the Mohs scale, so it scratches glass and is not scratched by steel. This is a raw cluster: nothing cut, nothing polished, the points left as they grew.

Amethyst (SiO₂), raw and unpolished

7 on the Mohs scale

Cluster, points intact, no cutting

Care

Treatment

None declared — written confirmation from the supplier is still being collected

Every stone carries a treatment line in its specification table. "None declared" means the supplier has not told us of any treatment and we are still collecting that statement in writing. If a stone has been heated, irradiated, dyed or resin-filled, we say which — a treated stone is not a defect, but it is a different object, and some treatments change how it should be kept.
