# DIA-99, $110.00 Sold!
Dims: 0.22x0.21x0.19" (5.66x5.30x4.88mm) .... Wt: 1.80ct (0.36g) .... Loc: Tschikapa, Kasai Province, Congo
This diamond cube is only slightly distorted, being ever so slightly rhombic, perhaps 10% flattened, and having a single small bump due to another diamond crystal intergrown with the cube. The color is nearly colorless, having only a hint of yellow, and the rough, multi-faceted surface hides any transparency - the diamond looks translucent. But when examined with a loupe and under a bright light, it appears that the crystal's interior may be largely transparent - not only do some sparkles pass through it, but a rainbow is visible at certain angles from light entering the far side of the crystal (I only see this with my loupe).
# DIA-107, $53.00 Sold!
Dims: 0.16x0.18x0.18" (0.41x0.46x0.46cm) .... Wt: 0.95ct (0.19g) .... Loc: Tschikapa, Kasai Province, Congo
This is a good cube of diamond, its form is distorted by two points of a second intergrown cube protruding slightly through three of its faces. It is translucent and a light gray in color. It also has a good luster and the surface is smoother than many natural diamonds.
# DIA-106, $42.00 Sold!
Dims: 0.16x0.14x0.16" (3.96x3.66x4.01mm) .... Wt: 0.75ct (0.15g) .... Loc: Tschikapa, Kasai Province, Congo
This cube of diamond is a single crystal, and its form is only moderately distorted, being a little tapered towards one end, and one corner seems to be missing (which is unlikely, as it is very difficult to damage a diamond). The real oddity is that in the center of the smaller face are two pits, readily visible with a loupe, which look like crystals of something else had been overgrown by the diamond, and subsequently disolved away. This seems incredibly unlikely to me, but that is what it looks like.
# DIA-105, $69.00 Sold!
Dims: 0.30x0.28x0.22" (0.77x0.70x0.57cm) .... Wt: 2.35ct (0.47g) .... Loc: Mbuji-Mayi, Congo
This diamond crystal is from Mbuji-Mayi, Congo (formerly known as Bakwanga, Zaire). It is a cluster of many rounded crystals, which have distorted shapes not easily described. The color is gray, it is translucent, and the luster is vitreous. Overall, the cluster has a somewhat pyramidal shape, and from one angle it has a distinct heart shape.
