Even though the stories of diamond mixing have been revealed to be a farce, it is important that people in the diamond trade are mentally secured and satisfied about the issue. In this regard, lot of technological progress has been made in the past few years. Several companies have introduced range of user-friendly diamond detection machines that does away with the need of expensive certifications in a grading laboratory. These machines can be used by anyone without being a gemologist or a spectroscopy expert. Furthermore, many of these machines are quite affordable.

Last year, De Beers and GIA came up with new diamond detection machines. GIA’s “DiamondCheck” is priced at USD 23,900. De Beers supplies “Diamond Sure”, “DiamondView” and “Automated Melee Screening (AMS)” devices. AMS is able to detect stones from 0.2 carat down to 0.01 carat and can take up to 500 carats at a time. Lease Fee for one unit of AMS for a 3-year contract was earlier USD 75,000. (Post original publication of this post, we’ve received a mail from IIDGR UK stating that this info is now almost a year old and AMS is now available for purchase for USD 55,000. Besides, there is a 3-year service and support fee of USD 10,000 per year)

Besides, there are several other diamond detection machines that are much more affordable even for small jewelers. ‘Gemlogis TAUPE’ is purported to be a better version of the HRD Antwerp D-Scope technology and is available online for USD 485.

Diamond Services Ltd., a Hong Kong based firm, provides ‘Diama Pen’ – a pen shaped laser beam pointer that is able to detect both HPHT and CVD stones. J. Kuzi, EGL Asia CEO mentioned that they had conducted series of tests using this instrument and found that “in all cases the testing results are consistent and highly satisfactory.” Diama Pen was offered for only USD 199.

WTOCD and HRD Research has also developed ‘D-Screen’ device that can detect all forms of diamonds from 0.2 to 10 carats at ~200 stones/ hour. Though exact price of the same is not known, it is termed as one of the most affordable diamond detection machines.

Almost all the leading diamond bourses and industry bodies globally have installed such diamond detection machines. HRD had distributed its D-screen to all diamonds bourses worldwide. GIA had given its Diamond Check machines to several bourses and associations like GJEPC has acquired AMS to be installed at Diamond Detection and Resource Centre (DDRC) in Bharat Diamond Bourse (BDB).

Though some questions have been raised earlier regarding the efficacy of these machines, De Beers “is confident that its technology detects all synthetic diamonds. GIA has also supported this claim while its own ‘DiamondCheck’ machine is asserted to be 100% accurate with an ability to determine the results in 10 seconds. Many of these detection machines are also able to detect any treatments done to diamonds.

There are numerous diamond detection devices easily available in the market from as low as USD 200 to a few thousand dollars. Instead of loosing sleep over any mixing dreams, it’s best to get a diamond detection instrument.

  1. With regards to the above article. I defer to the point that the ‘Gemlogis TAUPE’ is purported to be a better version of the HRD Antwerp D-Scope (D Screen) technology ….in fact Gemlogis had copied the D-Screen technology and HRD Antwerp had even send a legal notice regrading the same to the company. Soon HRD Antwerp will be launching a automated screening machine called M Screen…
