- Aquamarine (Rough and Cut Set)
- Thumbnail, various
- Mack Mine, near Rincon, San Diego County, California, USA
- Ex. William (Bill) Larson
A beautiful set of unusual gemmy crystals that nobody really would believe was from the County if it came with anything other than the pedigree of the biggest County collector and miner of our time. All have glassy luster, and glisten, in person. Bill Larson collected these specimens himself at this now-defunct locality, which is now part of Indian casino land.
