Quartz
Baskatong Quartz mine, Saint-Ludger, Le Granit RCM, Estrie, Québec, Canada
A misshapen, doubly terminated 'floater'. The side of the crystal in the photo exhibits multiple terminations, offsets, and growth features. The reverse side of the crystal has more 'normal' prismatic and rhombohedral faces. Collected from a cavity in massive quartz.
