- Ojuela Mine, Mapimi, Durango, Mexico
- Ex. Dr. Mark Feinglos
A thumbnail of this rare species of super quality, from famous finds at Ojuela in the 1970s! It is very hard to obtain this mineral today - it is much rarer even then legrandite, in my experience, on the market. This is a killer thumbnail example, too, in aesthetic pinwheel form and complete all around!
