8.43 ct Green Tourmaline - Oval

At 8.43 carats, this tourmaline from Brazil carries its green color through an oval cut, measuring 14.5 x 11.5 x 8.1 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. Its color was brought up by heat, a legitimate and accepted practice that the trade discloses and we disclose here.

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.
