13.51 ct Pink Tourmaline - Radiant

At 13.51 carats, this tourmaline from Nigeria carries its pink color through a radiant cut, measuring 19.9 x 11.1 x 8.2 mm.

Tourmaline takes a wider range of color than almost any other gem species, because its crystal will accept so many different coloring elements. Nigeria's gem fields rose to prominence in the 1990s and remain a significant modern source. 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.
