Man Claims Harry Winston Jewelers|Blew Sale Of World’s Largest Sapphire

LOS ANGELES (CN) - A man who says he is co-owner of the largest sapphire in the world, the 733-carat Black Star of Queensland, says Harry Winston jewelers and its vice president Goli Parstabar blew a $5 million sale by telling the buyer that plaintiff Jack Armstrong did not really own it, and having Armstrong removed from Winston's Rodeo Drive store.

Armstrong also nominally sues Gabriele Grohe-Guiton, as an involuntarily plaintiff, saying she is the co-owner of the gem and he wants to avoid a multiplicity of lawsuits. He is represented by Devin Weisberg.

This is an amended complaint of a lawsuit that Armstrong filed pro se earlier this week.
