16.63 ct Bi-color Tourmaline - Emerald Cut

At 16.63 carats, this tourmaline from Brazil carries its bi-color face through an emerald cut, measuring 21.0 x 11.3 x 7.6 mm.

Tourmaline takes a wider range of color than almost any other gem species, because its crystal will accept so many different coloring elements. 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.
