A tech company in Hong Kong has created a device that can determine if yellow diamonds are lab grown or imitation.

According to reports, Diamond Services of Hong Kong say their Diamond Natural Device (DND) is the first to be able to identify man made or treated yellow diamonds.  The system works by lowering the temperature of the stones with liquid nitrogen, allowing differences in the stones to be identified.

Reports indicate the process can only be completed in a lab setting and that equipment needed to perform the tests will not be sold to customers.  The DND process allows for the scanning of loose or set stones in large quantities.
