Myerhofferite after Inyoite
Out of stock
This is a somewhat uncommon alteration mineral collected by Ken in 1975. According to Moore (Compendium of Mineral Discoveries), these pseudo crystals seldom exceeded 2.5cm for the more aesthetic specimens. There are two examples in this collection, this thumbnail and a monster cabinet piece (to be seen in a later post). Rarely found in the market today. Ex Ken Roberts collection.
