From light to vivid green!
Green Tourmalines have a range of colors from yellowish-greens, to greens to olive-greens and are available from light to medium tones.
Tourmalines are part of a family of closely related mineral species with the same crystal structure but with different chemical and physical properties.
Most Green Tourmalines are Elbaites that are colored by iron. A rare variety of Dravite that is colored by the trace elements vanadium and chromium is known as Chrome Tourmaline.
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!
