2.38 ct Yellow Tourmaline - Marquise

At 2.38 carats, this tourmaline from Nigeria carries its yellow color through a marquise cut, measuring 10.2 x 7.1 x 6.3 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 wholly untreated, its color finished by geology rather than by any furnace or enhancement.

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.
