Large high quality specimen. One surface is covered in flat botryoids on small patches of heterogenite with a small malachite "bush". Some chrysocolla is also in-matrix, and small side vugs reveal bright blue, gemmy vugs of gem silica

Gem silica and chrysocolla are typically found in copper ore deposit veins, where they can take on a massive, crusted, or botryoidal form. Gem silica (also known as chrysocolla chalcedony) is the druzy or gemmy form of chrysocolla with quartz, and it is exceptionally more rare than its constituent components.

Locality: Kulukuluku, Congo
Mass: ~710g (best estimate, this specimen maxxed out my mineral scale :( )
Dimensions: 120x80x47 mm
Size classification: Large cabinet

Dimensions are approximate, as minerals come in unique, irregular shapes. Thank you for understanding!
