A large, sharp, very pale green single crystal of Prehnite in blocky form. From the Jeffrey Mine, where some of the worlds best and largest Prehnite crystals were found. No damage and with good luster this is a nice thumbnail that shows the habit well. Prehnite is a rather common mineral but crystals over a half centimeter are very rare and only come from a few finds.
