This remarkable bicolored tourmaline comes from the recent finds in the Democratic Republic of the Congo. We work to source this rough directly from the small-scale artisanal miners at this new find, and have selected only some of the largest and finest pieces of tourmaline mined there.  This gem was cut from a gorgeous bicolored crystal that transitioned from a reddish pink on one end to a beautiful pastel mint blue-green color.  In order to highlight this gorgeous color transition I spent many hours creating and optimizing a new design; and the results were well worth the effort.  The gem is extremely clean with just a few tiny crystal inclusions and one tiny feather that are just barely visible to the naked eye.

This tourmaline is faceted in a custom rectangle cushion design named “Aquilone;” the result is a glittering beauty of a gemstone. The gem weighs 15.20 carats and measures 23.4 x 10.5 x 8.1 mm. It would make for an impressive centerpiece pendant or simply appreciated as a collector’s gemstone.
