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.
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.
Unusually, the Incomparable Diamond made an appearance on eBay in November 2002, though it remained unsold with a reserve of £15 million pounds sterling. The auction itself was quizically vague and showed a poor-quality photo.
