- Incomparable Diamond
In 1970, Louis Glick acquired the 890 carat (178 g) rough (407.48 cut) Incomparable Diamond, at that time the world's fourth largest rough
diamond .cite web | title=Louis Glick & Co. official website | url=http://www.louisglick.com | accessmonthday=April 4 | accessyear=2007] The principal 407-carat stone remains the third largest gem-quality faceted diamond in the world.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.cite web | title=The World of Famous Diamonds and Other Gems | url=http://famousdiamonds.tripod.com/incomparablediamond.html | accessmonthday=April 4 | accessyear=2007]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.cite web | title=GIA Laboratory | url=http://www.gia.edu/gemtradelab/108/what_we_do.cfm | accessmonthday=April 4 | accessyear=2007]
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.
