11.45 ct Green Tourmaline - Rectangle

At 11.45 carats, this tourmaline from Brazil carries its green color through a rectangle cut, measuring 27.1 x 7.3 x 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. 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 filmed by Caveman Gems in good light, shown as honestly as a screen allows.
