Description

This rich, dark-green, velvety specimen of solid malachite crystals in a hemispherical aggregate.

Some complexly crystallised fibrous structure gives the sides and bottom surfaces of the malachite a chatoyant luster.

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