Most Blue-Green and Teal Tourmalines are Elbaites.

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.

Tourmaline is one of the birthstones for October and celebrates the 8th Anniversary.
