Mint Tourmaline & Mint Chrome Tourmaline
An attractive pastel green to bluish-green
Mint Tourmalines have a range of pastel colors in the bluish-green part of the spectrum.
Most Mint Tourmalines are Elbaites. A rare variety of Dravite that is colored by the trace elements vanadium and chromium is known as Mint Chrome Tourmaline
Tourmalines are part of a family of closely related mineral species with the same crystal structure but with different chemical and physical properties.
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.
Lots of choice in colors for October birthdays!
