The premier source for mint tourmaline is Namibia.
These rare gemstones are coveted across the globe.
The unique bluish-green to greenish-blue color of this tourmaline is due to the trace elements of iron and titanium.
Tourmaline is formed in granite-containing pegmatites, a rare igneous rock, and these conditions lead to long slender crystals.
Great skill is needed to cut these gemstones on the right axis to obtain maximum color.
Only a handful of people in the world have the expertise required.
