1.93 ct Red Tourmaline - Round

At 1.93 carats, this tourmaline from Nigeria carries its red color through a round cut, measuring 7.8 x 5.3 mm.

Tourmaline takes a wider range of color than almost any other gem species, because its crystal will accept so many different coloring elements. Nigeria's gem fields rose to prominence in the 1990s and remain a significant modern source. It is entirely untreated; no heat, no enhancement, the color exactly as the earth made it.

Its exact combination of color, cut, and origin is its own, the kind of center stone you choose on purpose and build a piece around. Hand-selected and photographed by Caveman Gems in good light, shown as honestly as a screen allows.
