Mineral Specimen #6259 Tourmaline (Elbaite) with Inner Ring Pseudomorphed to Lepdiolite
Pederneiras mine, Sao Jose da Safira, Minas Gerais, Brazil
8.3 x 1.8 x 2.1 cm
A rather unusual Tourmaline crystal with four distinct, concentric layers in its interior. The inner core is a rosy, pink color. Around this core is a thin layer of dark colored material. Next comes a ring which is composed of more of the pink material. In about a third of this ring, the Tourmaline has altered to Lepidolite. The outer layer is composed of very dark green colored Tourmaline except at the terminated end where it becomes much darker, essentially black in color except with a purple cast in the multitude of sub crystals of which the termination is composed.
Condition: Very Good
Flaws: Nothing Appreciable
