A miniature with great form and an unusual combination of specie. The specimen is fully covered by Mottramite in a botryoidal form that has enclosed underlying Wulfenite crystals. The form of the Wulfenite blades is still evident but they are not visible on the specimen surface. A very unusual replacement, and another example of the amazing processes that have taken place at Mina Ojuela. No damage and a fine example of Mexican Mottramite.
