Incomparable Diamond

In 1970, Louis Glick acquired the 890 carat (178 g) Incomparable Diamond, at that time the world's fourth largest rough diamond.[1]

Alternate sources claim that this stone was only discovered in the early 1980s in the town of Mbuji Mayi in the Democratic Republic of Congo, by a young girl playing outside her uncle's house, where rubble from a nearby diamond mine had been dumped.[2]

The stone was cut by a team led by Marvin Samuels, who co-owned the stone along with Donald Zale of Zales Jewellers and Louis Glick. In November 1984 the finished stones were put on display: a single golden diamond of 407.48 carats (81.496 g) in a 'triolette' shape, and fourteen additional gems. Notably, the satellite stones cut from the Incomparable varied greatly in colour, from near-colourless to rich yellow-brown.

The largest of these stones still bears the name 'Incomparable Diamond', and was graded by the GIA as internally flawless in 1988.[3]

Unusually, the Incomparable Diamond made an appearance on eBay in November 2002, though it remained unsold with a reserve of £15 million pounds sterling.[4]
