Diamonique
Diamonique is the brand name used by television shopping network QVC for their cubic zirconia simulated diamond and other synthetic gem products (cubic zirconia is a common type of gemstone substitute). QVC acquired the manufacturing facilities, proprietary technology and trade name rights from MSB Industries, Inc. in 1988.[1]
The name "Diamonique" was also used as the brand name of a synthetic garnet that was diamond-like in appearance and manufactured in the 1970s.
