Peruvian Treasures

Between the recent Peruvian finds of saturated chrysocolla, deep green fluorite, and mirror-like pyrites, this region of the world is definitely experiencing a resurgence in interest from mineral collectors. We blended a combination crystals from newer finds and old classics (think old Peruvian rhodochrosites from the Jack Halpern collection, plus new chrysocolla specimens from Tentadora) to showcase a range of beautiful material from an assortment of Peruvian localities.

Don't miss out on your next treasure.
