Diamond Services introduces new lab-grown diamond identification
system, expands accurate detection to light-brown colour ranges

Diamond Services, the Hong Kong-headquartered developer of technological systems and services for detecting laboratory grown, imitation and treated diamonds, has announced that it is introducing into its laboratories a new device developed by its own research and development team, which improves the range of detectable merchandise to include all rough and polished stones in the lower yellowish-to-light-brown colour ranges. Like many other devices being used in the market, the new system provides solutions in the colourless to near-colourless range of diamonds, but the company stresses that this is the first device that also provides solutions for diamonds in the light-brown colour range.

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."

Like all the systems developed by the company, the DND system is capable of scanning loose diamonds and diamonds set in jewellery, in large quantities and with no size limitations, in short periods of time.

Diamond Services was established in Hong Kong in 2012 with the goal of developing technological systems to assist in the screening and identification of synthetic diamonds, as well as diamonds that had been colour-treated using High Pressure, High Temperature (HPHT) technology. It began offering synthetic screening services in 2015, through its headquarters in Hong Kong and in the United States. Since the start of this month, the company has begun providing services to Indian jewellery companies from a new location in the SEEPZ industrial zone in Mumbai.
