Emke Mine, Ongangja, Seeis, Khomas Region, Namibia
This rare gemstone is a companion piece to Lot 87011 on an earlier section of this auction. All large gemstones of this mineral are most likely derived from this one-time-only find at the Emke Copper Mine. The stunning, deep ruby red color can best be appreciated under strong incandescent lighting or in transmission. The extremely high Refractive Index (2.849) is way higher than Diamond and as a result, the luster is very clearly a sub-metallic one that competes with the deep color for dominance. The stone is quite 'clean' and the cutting is well done, particularly for such an exotic material.
Overall Measurements: 22.7 x 20.2 mm, 93.6 cts. Offered at no reserve.
Provenance: C. Carter Rich [Hoppel Catalog # G1894]
[Scale: 1 inch, with mark at 1 cm]
