Cuprite, Otjimbingue, Namibia

A red-copper ore containing mineral, this striking gem has a very high refractive index. The present pear-shaped stone is a very pretty example which exhibits a characteristic metallic luster and a deep red body color for which the mineral is known.
Weighing approximately 20.56 carats and measuring 20.0 x 12.5 x 8.0mm
