Cristobalite
Cougar Butte, Cascade Range, Siskiyou County, California, United States.
62 x 50 x 40mm

Excellent specimen of Cristobalite and Fayalite in Obsidian. Cristobalite crystallized at high temperature results from devitrification (loss of silica) of the Obsidian. Note the smaller Cristobalite nodule has been repaired (placed back into its socket).
