(IDEX Online) - A pioneering new app uses facial recognition-type technology to positively identify diamonds and combat fraud.It allows anyone in the jewelry industry with an iPhone or iPad and a $50 outlay to start registering and verifying diamonds using a special viewer that fits over the camera lens.Tech firm GemEx says its patented DiamondEye is the only affordable ID system in the marketplace for diamond traders, retailers and consumers. It protects jewelers from allegations of diamond swapping from customers bringing in repairs, and from criminals who try to switch stones."DiamondEye protects the jeweler from criminals trying to switch diamonds," the company said."When a diamond is returned, girdle engravings can be forged. Lab-grown or simulants can be difficult to detect. Within minutes, DiamondEye verifies it is the diamond you sold to them."Users order a registration kit, download the DiamondEye app, fit the viewer on their device and register their diamonds on the SkyVault database in a matter of minutes.DiamondEye's Prong Check will also confirm that the diamond is secure in its setting.Randall Wagner, CEO of US-based GemEx Systems said: "We have processed over 5m diamonds through our IdentiView technology, which is an integral part of GemEx Light Performance. "Very similar to facial recognition system, DiamondEye now brings IdentiView technology to anyone with an iPhone or iPad."
