Description
Locality: 
Rowley Mine, Theba, Maricopa County, Arizona, United States of America

Miniature (4.5-7 cm)
Size: 
5 × 3.5 × 2.5 cm
Description

Very brilliant globular aggregates formed by orange mimetite crystals. Interpenetrated and with an excellent brilliance. I have analyzed this sample because some mimetite from this locality have shown a large content of Ca. In this sample no Ca present. Accompanied by some wulfenite crystals.
