ALROSA DIAMOND INSPECTOR showed high results in the ASSURE testing program by the Diamond Producers Association (DPA)

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 with analogs, Russian device suits retail shops, pawnshops, distributors, gemological laboratories, jewelry manufacturers.

The testing was held in July 2019 as a part of the 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, among them samples unavailable on the market, which were grown by using the 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 uses three optical method of identification, so that it can separate 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.

Rating accuracy

According to the results of testing, ALROSA DIAMOND INSPECTOR showed an almost one hundred percent result of 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 belongs to the category of portable devices with the dimensions of 15 * 25 * 10 cm and weight of 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.

Stone parameters

ALROSA DIAMOND INSPECTOR can analyze natural diamonds, synthetic diamonds and non-diamond imitations (simulants) of any shape. The device analyzes stones in a size range from 0.03 to 10 carats and a color range from D to J (colorless and near colorless). It should be noted that these ranges are the most frequent in the retail jewelery.


The price of ALROSA DIAMOND INSPECTOR (5,799 $) is significantly lower than the price of analogs.
