Knowledge is power: The global diamond industry responds to its synthetic counterpart

The most difficult misconception to overcome has been marketing; many retailers still believe nothing can beat the “a diamond is forever” tagline or that a diamond must be naturally-mined to be equivalent to love. The vast majority of synthetic diamond retailers are targeting a 25-to-35-year-old consumer with a message highlighting the eco-friendly and non-conflict nature of synthetic diamonds. Though the notion of love is not yet in this marketing message, I do think it’s only a matter of time before it is. The link between sales and stones has always been an emotional one, so once synthetic diamond marketers figure out how to target their consumers’ emotions, they will have made the next leap—this is what made naturally-mined diamonds shift from being a stone for a ring to a commoditized expression of love.

Leading the way

As trade leaders continue to highlight the growing issue of synthetic diamonds, behind the scenes, many of the major players in the mining, manufacturing, and gemmological sectors are establishing screening facilitates within their factories and making these resources available to a broad range of trade members, ensuring confidence in the rough and polished diamond sectors.

Though leading global gemmological laboratories continue to be vigilant in screening for synthetics, most diamond cutters, sightholders, wholesalers, and individuals working with diamonds acknowledge the primary threat with synthetics to be smaller-sized diamonds between one and 10 points.

The Gemological Institute of America (GIA) and De Beers, through the International Institute of Diamond Grading and Research (IIDGR), have established synthetic screening services at a number of locations to allow diamond trade members access to this valuable service.

In India, many diamond industry sites have invested in screening devices. These are used daily to ensure all parcels of diamonds are free of synthetics. Unfortunately, this still doesn’t address the new growing concern there has been an increasing use of synthetic diamonds mixed with natural stones in finished jewellery.

It is impossible to screen small-set diamonds in a cost-effective method, as this would require the stones be unmounted to allow accurate testing. Though many of these items have been bought and sold in local markets, there is a pressing fear mixed synthetic and natural diamond-set jewellery is being sold to foreign buyers. This will further erode consumers’ confidence in the products they are buying.

With a level of uncertainty as to when a testing protocol will be established to screen small-set diamonds, you can be certain legal actions will be taken by consumers who were sold jewellery without disclosure of synthetics when the time and technology comes.

Knowledge is power

In spite of the emerging growing issues with synthetics, there is a unique opportunity for jewellers to enhance their knowledge regarding synthetic diamonds and how it can impact business. Investing in knowledge and equipment can serve as a great first step in ensuring one can face this new challenge unharmed. Over the past year, there have been many hand-held devices screening technologies introduced to the market and they are an excellent investment.

With technology quickly changing in a diversifying industry, information really is the key to overcoming the obstacle of synthetic diamonds, after all.
