Native Diamond

Province, Congo

This diamond cube is only slightly distorted, being ever so slightly rhombic,
perhaps 100%
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 loupe.
