18.77 ct Bi-color Tourmaline - Cushion

This 18.77-carat tourmaline is cut as a cushion measuring 23.4 x 9.2 x 8.6 mm, showing a bi-color face, sourced from Brazil.

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 heat-treated, a common and honest preparation across the colored-stone trade, disclosed on every listing.

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 films it in good light, to give you the truest look a screen can.
