16.67 ct Bi-color Tourmaline - Emerald Cut

At 16.67 carats, this tourmaline from Brazil carries its bi-color face through an emerald cut, measuring 16.2 x 11.7 x 9.4 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 is entirely untreated; no heat, no enhancement, the color exactly as the earth made it.

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 photographed by Caveman Gems in good light, shown as honestly as a screen allows.
