XL Malchite with Quartz from the Blue Wing Mine, N.C

The blue wing mine is a minor American classic product of only from 1900-1909. There is an entire blog post going over the history of these specimen and their rarity. 
This is the LARGEST specimen from the blue wing I’ve seen. Amazing quartz and calcite points. The malachite forms both in concentric rings and ribbons over the calcite and quartz. Over 2.5lbs
