Diamond Services, the Hong Kong-headquartered developer of technological systems and services for detecting treated diamonds, laboratory grown diamonds (LGDs) and simulants is introducing a new device which widens the range of detectable merchandise to include all rough and polished stones in the lower yellowish-to-light-brown colour ranges.
Like other detection apparatus developed by Diamond Services, the new system, called DND (Diamond Natural Device), scans diamonds at the temperature of liquid nitrogen, which the company has shown provides a higher degree of accuracy than detection devices which examine diamonds at room temperatures.
"To provide as accurate results as possible, we insist that all diamonds being tested to detect the possible presence of synthetically-produced goods be examined at temperatures in a liquid nitrogen atmosphere," explained Joseph Kuzi, Diamond Services' founder and president. "Since this can only be done reliably and safely in a proper laboratory setting, we have selected not to sell the equipment we develop, but rather to use it exclusively as part of the service we provide the trade. The new DND system improves that offering, widening the range of goods that can be screened to include all goods at the lower end of the standard colour range."
