Description

Sharp, spear shaped, jet black goethite crystals in a well-shaped agate. The contrast is striking, as the vug is very clean of coatings and the quartz crystals display glass luster. The agate shows a thin white-to-brown banding towards the external wall of the specimen.

A Moroccan classic, in very good conditions!
