Verdelite Tourmaline - Chia Mine 25.9 Grams

This stunning green tourmaline (verdelite) from the Chia Mine in Sao José de Safira, Minas Gerais Brazil is especially perculiar. Some specimens from this locality display the "Schiller Effect", a phenomenon commonly displayed in varieties of feldspar like peach or black moonstone. It is most notable when under bright light, like a camera flash.
