Summary

Description
English: Diamond
Locality: South Africa (Locality at mindat.org)
Size: thumbnail, 1.5 x 1.5 x 0.4 cm
Diamond (Macle twinned)
This rare twinned diamond crystal is not only stunning, but is also rather thick at 4.2 mm in thickness, to have such clarity. It is twinned in a formation called "macle twinning", more common in spinels and quite rare in other gem species. The result is that instead of looking octahedral, it looks like a sharp triangle. It is exceptionally clean throughout, with only a few extremely slight carbon inclusions; and you could call it gemmy and literally mean "gemmy" when you say it. The triangular form is unusually equant for a stone of this size, and it "looks" naturally cut. In fact, a recent vogue in jewelry is to wear such natural diamonds in fancy settings, without cutting and faceting them. This could be one such showpiece, if mounted in a setting. It certainly is the biggest diamond of any quality that I have seen for available on the open market as a specimen in the 3 years or so since I last had one of these crystals. The specimen is 9.94 carats.
