4.97 ct Green Tourmaline - Trillion

This 4.97-carat tourmaline is cut as a trillion measuring 12.1 x 10.3 x 7.3 mm, with a green body color, sourced from Congo.

Tourmaline takes a wider range of color than almost any other gem species, because its crystal will accept so many different coloring elements. It is wholly untreated, its color finished by geology rather than by any furnace or enhancement.

One of a kind, it exists exactly once; there is no second example to size up or down. It is the rarer object, and the kind of gemstone that becomes an heirloom. Caveman Gems hand-selects every gemstone and photographs it in good light, to give you the truest look a screen can.
