1.16 ct Green Tourmaline-Paraiba - Square

At 1.16 carats, this Paraiba tourmaline from Brazil carries its green color through a square cut, measuring 7.1 x 7 x 2.5 mm.

Paraiba tourmaline owes its electric glow to traces of copper, a coloring agent almost no other gemstone carries. Brazil has been one of the most prolific colored-gemstone sources in the world for a century, and still turns up new material on a regular basis. It carries no treatment of any kind, so the color you see is the color that came out of the ground.

A single natural gemstone with no duplicate behind it; once it is set or collected, there is no other. It will outlast everyone who owns it, which is most of what an heirloom really is. Hand-selected and filmed by Caveman Gems in good light, shown as honestly as a screen allows.
