Intergrown 'pinwheels' of Zincolivenite from a new find at the Milpillas Mine (yes - with a rise in Copper prices the mine reopenned and they hit a zone of great zincolivenite crystals). There were a few styles found, one of which were toothy clusters like these, reminiscent of Tsumeb. This nice thumbnail is composed of about 5 interconnected pinwheel clusters.
