It supplies bothloose stones and jewelry to some of the world's leading jewelers, the site says. However, the company lost its sightholderstatus earlier this year and is now only an accredited buyer, meaning it onlypurchases supply on an ad hoc basis, Bloomberg said. Exelco supplies retailers such as Signet Jewelers with theTolkowsky Ideal Cut diamond - named for Marcel Tolkowsky, who invented the ideal-cutround brilliant diamond in 1919. His great nephew, Jean-Paul Tolkowsky, aseventh-generation diamantaire, co-founded Exelco in 1993 with Leon and LiorKunstler.
