17.40 ct Bi-color Tourmaline - Emerald Cut

This 17.4-carat tourmaline is finished as an emerald cut measuring 17.3 x 13.5 x 7.4 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 entirely untreated; no heat, no enhancement, the color exactly as the earth made it.

There are not many gemstones like it, and there will not be more. Shown in good light, with its full history available before you commit.
