Natural Indicolite Blue Tourmaline 1.78ct Octagon Cut

This natural indicolite tourmaline is presented in an octagon cut and displays a deep, inky navy-blue color with characteristic indicolite darkness. The stone absorbs light powerfully into its saturated blue-teal body, appearing almost black in overhead light while revealing its deep midnight-blue or teal-blue character when light is passed through from below. The surface shows clean facets with only minor natural inclusions.

Indicolite is the rare blue variety of tourmaline, named from the Latin for "indigo," and is one of the most sought-after color varieties of the species. This stone from Mozambique is completely untreated. It is an ideal choice for collectors, for bold ring designs, or for designers who work with deep, dark-toned gemstones. A beautiful and rare natural blue tourmaline.
