Wendwilsonite

- Morocco
- 5.3 × 5.2 × 2.8 cm – Small cabinet specimen (under 10 cm)
Wendwilsonite is a hydrous calcium magnesium arsenate, dimorphous with talmessite. Were the mineral free of cobalt substitution, it would be colorless. Fortunately minor cobalt substitution for magnesium leads to a rich magenta color. Dunn et al. (1987) named the mineral after Dr. Wendell E. Wilson, editor and publisher of the Mineralogical Record.
This specimen hosts wendwilsonite crystals to 6 × 8 mm on crystallized dolomite. These crystals are certainly above average in size for the species. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
