Here is a substantial Erongo quartz from the same pocket as the iron patina specimen in this collection, with a beautifully complex natural surface and fine tourmaline and feldspar associations.

The crystal has a broad, tapered form with the same wrinkled growth and chunky structure seen in the other material from this find. Across much of the surface is a very thin milky patina, interrupted by strong geometric contact imprints that create sharply defined windows, steps and recessed patterns through the quartz. These impressions give the specimen a beautifully sculptural surface.

Fine black tourmaline needles are scattered across parts of the crystal, while pale feldspar is concentrated around the lower sections and base. The contrast between the soft milky coating, darker tourmaline and clearer exposed quartz gives the piece a particularly complex appearance without obscuring the underlying form.

What makes this specimen especially interesting is the relationship between the contact growth and the preserved quartz beneath it. The surface doesn't read as uniformly coated or etched, but as a record of minerals growing closely against the quartz during formation, leaving behind strong geometric impressions and irregular interruption patterns. It is a highly textural and very characteristic example from this particular Erongo pocket.
