Description

Shattuckite and dioptase from Kaokoveld in Namibia.

On a schattuckite layer there are many crystals of dioptase placed - some ongrowing, some partly beneath the layer.

The specimen forms to some extend a "hole", where you can find also both - shattuckite and dioptase inside. The dioptase crystal show the typical Namibian bright, transparent green.

Shattuckite often appeared sole or in combination with malachite - but I think you will not too often find a matrix like this.
