- Thumbnail, 1.6 x 1.3 x 1.2 cm, 19.02 ct
An excellent, sharp diamond octahedron, weighing in at 19.02 carats. The crystal has edges of 1.0 to 1.2 cm, and is 1.6 cm tip to tip. Even when minimally backlit, there is a nice gemminess and translucency. The adamantine luster is superb, as you would hope! This is a stunning, relatively large and sharp thumbnail specimen for a diamond crystal, that does not break the bank to own one of good size. I got it years ago, and probably could not replace it today at the price.
