Tourmaline
Tourmalines are the world’s most colorful gemstones, ranging from transparent to pitch black.
The pegmatite-rich Cruzeiro Mine yields a rainbow array of gems, and much of our production is green tourmaline, ranging from yellow-green to the highly sought-after blue-green and true blue, also known as indicolite.
We also produce lovely pink tourmaline, ranging from baby pink to deep, rich fuchsia, as well as an array of bicolor tourmalines.
With a Mohs hardness of 7.5, tourmaline is beloved by jewelers and consumers for its range of colors and its durability.
