This transparent, markedly yellow, diamond with excellent luster clearly shows off its octahedral form. It does have some inclusions but this is a large uncut diamond of almost 3 carats (2.93) and I think you could even get a fair-sized stone out of it. As a specimen, though, it is much more rare and desirable!? Rare diamond crystal, at the price, I think, of even a traditional white stone. Ex. John Saul Collection
