Clarification of Opinion Suggesting Equal Price For Small Natural & Synthetic Diamonds

Two weeks ago, IDEX Online published an opinion piece by Thierry Silber, CEO and founder of Diamaz International and Madestones, entitled "How to Kill Four Birds With One Stone". Here Silber makes the following proposal on the way to tackle the heated issue of undisclosed mixing of natural and synthetic diamonds: "Why not remove the mixing issue by selling both types of smaller diamonds at the same price up to a certain size?" The main problem as he sees it is the cost of detection involved in screening for synthetic diamonds, particularly for smaller manufacturers.

Opinion pieceGradingManufacturingPolished

Anyone telling you that lab created diamonds are cheaper [than natural] is straight out lying (they just use weaker certificates to make inflated quality claims; the oldest scam in the book) ... You shouldn’t ignore value entirely. Say an average natural diamond retains roughly 50% of its value after purchase. Eventually the value of the diamond will rise, so if you ever try to sell it, you should be getting at least half (or possibly much more) of the original purchase price. Lab-created synthetic diamonds have no resale value. So, from a value perspective, you would need to buy the lab-created diamond at a massive discount to justify giving up the value retention of natural diamonds ... The companies selling lab-grown diamonds claim that their diamonds are 30-40% cheaper. That is an outright lie. So If you are planning on buying a diamond and looking to get the best bang for your buck, natural diamonds are a far better choice than man-made diamonds.

I have been a strong proponent of generic diamond marketing. Fragmenting the diamond market with diamond brands is having a negative effect on the consumers’ perception of generic diamonds. Currently, we are not only witnessing diamond brand wars but a new war is developing involving diamond reports. De Beers is taking on the GIA by opening their grading facilities to the general trade and Martin Rapaport is taking on the world with his new Investment Diamond Report ... These reports, like branded diamonds, are harmful to the marketing of generic diamonds. De Beers will market their report as superior to GIA. Rapaport will promote GIA as a secondary and a weak report. This new war of reports will cause consumer confusion and distrust. Put succinctly the consumer will suffer from ‘paralysis by analysis’. Rather than working together to encourage the sale of diamonds, our industry is continuously finding new ways to fragment and denigrate itself while destroying consumer confidence.
