Description

The rich, dark-green, velvety specimen of solid malachite crystal in a hemispherical aggregate. The concentric swirls have a chatoyance to them that follows the light as it plays across.

The chatoyance effect is very noticeable here, with seemingly shifting dark and light spots as you twist it under the light.
