The DMIA calls for a meeting regarding synthetic diamonds. This comes in response to tainted diamond pipelines. Also, additionally, relating to the sale of synthetic diamonds. The DMIA is short for, the Diamond Manufacturers and Importers Association of America. A vast majority of jewelers have responded positively to putting enforceable measures in place to prevent the sale of synthetic diamonds as natural diamonds.
According to the DMIA, the organization has revived confirmations from the Jewelers of America (JA). As well as, the Manufacturing Jewelers & Suppliers of America (MJSA), and The American Gem Society (AGS). Moreover, the Jewelers Vigilance Committee (JVC) agreed to the meeting and proposed measures. The Gemological Institute of America (GIA), The International Gemological Institute (IGI) and European Gemological Laboratory, heavyweight's in the diamond industry have also thrown support behind these new initiatives. The meeting is under the banner of the DMIA. The Diamond Dealers Club of New York (DDC), the Indian Diamond and Color Stone Association (IDCA). As well as the Natural Color and Diamond Association (NCDIA).
Tainted Diamond Pipelines and Detecting Synthetics Diamonds
Tainted diamond pipelines are a major concern for the diamond industry. Moreover, only to determine if a diamond is natural or if it has to go to a laboratory for further identification. Percentages of colorless to near colorless stones of a parcel that have to go to a laboratory vary widely, anywhere from 10 percent to 30 percent. Colored diamonds have to go to a laboratory to determine authenticity.
Tainted Diamond Pipelines and Methods Used
As of now, there are two methods used for screening diamonds. They are the UV-VIS-NIR absorption (also used in De Beers AMS) or FTIR absorption measurement (used, for example, in GIA’s Thermo-DiamondCheck). The UV-VIS-NIR absorption method is superior, as nitrogen in the ppb range can be detected. Furthermore, De Beers states clearly that its AMS system can only screen near-colorless to colorless diamonds. Furthermore, GIA does not state if its DiamondCheck can only screen near colorless to colorless or also colored diamonds.
There have been several press releases that reported that the DiamondCheck system can identify synthetic and HPHT treated diamonds, which is not the case with that system and is a false statement. Using photoluminescence as a screening method can in many cases give inadequate identification diagnosis. Therefore, this method is not a suitable primary method for screening diamonds but used as a second/additional method for identification.
