In a recent episode of the crime show CSI, an unscrupulous wife switches her rather large engagement diamond for a paste imitation. She was summarily carted off to jail, but only because the forensic engineers knew how to tell a diamond from cubic zirconium. Plus, she killed somebody. Girls looking to repeat the stunt better think twice now. Galil has reportedly supplied its PCI bus motion controller to a company that is developing an excimer laser diamond marking system for etching characters and graphics on diamonds for identification purposes. While this type of marking is not revolutionary, the new system reportedly will cost ten times less than existing units—thanks to a complete redesign involving new motion control technology. The lower the cost, the more units sold, the more diamonds marked, and, presumably, the less insurance fraud.
