18.94 ct Bi-color Tourmaline - Slab

This 18.94-carat tourmaline is shaped as a slab measuring 22.7 x 22.0 x 4.0 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 wholly untreated, its color finished by geology rather than by any furnace or enhancement.

No two of these line up the same way on color, cut, and origin at once, which is what makes choosing this one feel deliberate. Caveman Gems hand-selects every gemstone and photographs it in good light, to give you the truest look a screen can.
