- Quartz Included By Montmorillonite
- Cabinet, 14.2 x 5.9 x 4.5 cm
- White Queen Mine, San Diego County, California, USA
- Ex. William (Bill) Larson
A classic of San Diego pegmatites, these odd pink-colored quartzes are colored by dispersed inclusions of Montmorillonite, and historically were often sliced and diced for sale in pieces to the locals. This is a really large, relatively elegant piece of good quality.
