A classic Milarite specimen from the Valenciana Mine in Mexico. This specimen hosts a few rather lustrous, hexagonal, soft yellow-green color crystals of Milarite sitting atop porcelain-like, lustrous, sharp crystals of Adularia (var: Valencianite) with Quartz. The Adularia from this mine was distinctive enough that it earned a honor of being named after the locality. The Milarite crystals measure up to 8 mm across, which is good sized for this locality in my experience. Ex. Brian Kosnar Collection.
