The first Russian portable instrument for diamond verification, ALROSA Diamond Inspector, showed high results in the ASSURE testing, performed by the independent laboratory UL Verification Services, Inc. in Boston (USA). Due to three optical methods of analysis, ease of use and low cost in comparison to analogs, Russian device suits retail shops, pawnshops, distributors, gemological laboratories, jewelry manufacturers, corporate website reports
The testing was held last July within ASSURE Program of Diamond Producers Association (DPA). This program aims at the development and application of unified standard evaluation of the effectiveness of tools and special equipment for diamond identification.
In total, almost 1,400 samples were involved in the ALROSA Diamond Inspector testing process, including natural I/II type diamonds, synthetic diamonds including samples unavailable in the market, which were grown through applying most advanced technologies, and non-diamond imitations (cubic zirconias, moissanites, etc.).
Moreover, UL Verification Services, Inc. lab specialists tested over 20 devices of various manufacturers, dividing them into three groups. ALROSA Diamond Inspector employs three optical methods of identification, so that it can distinguish natural diamonds from synthetic diamonds and from non-diamond imitations (simulants). ALROSA Diamond Inspector was referred to the third group of devices with the broadest functionality.
According to the results of testing, ALROSA Diamond Inspector demonstrated a nearly absolute accuracy in detecting natural diamonds (96.4%), accurately referred synthetic diamonds (100%) and was the only device that showed one hundred percent result in detecting non-diamond imitations (simulants).
ALROSA Diamond Inspector is a portable device 15 by 25 by 10 cm weighing 1.8 kg in a plastic case and 3.1 kg in a metal case.
Testing of stones in ALROSA Diamond Inspector is carried out manually. An analysis of one stone takes 45 seconds, after which the instrument automatically interprets the results using a complex mathematical algorithm for spectral analysis and gives a ready answer on the screen. ALROSA Diamond Inspector can analyze both loose and mounted stones. It does not require gemological knowledge.
The device can analyze natural diamonds, synthetic diamonds and simulants of any shape ranging from 0.03 to 10 carats and with a color range from D to J (colorless and near colorless).
The price of ALROSA Diamond Inspector of $5,799 is significantly lower than the price of analogs.
