Tourmalines are part of a family of closely related mineral species with the same crystal structure but with different chemical and physical properties. Most Grey Tourmalines are from the Elbaite variety.

Since Tourmaline grows in long crystals referred to as “pencils” they are frequently cut as elongated emerald cuts that are perfect for pendants, earrings and even some rings.

Tourmalines are found in many different locations around the world including Brazil, Nigeria, Mozambique, USA (California, Maine), Congo, Tanzania, and has one of the widest color ranges found in gemstones.
