A Case of Knowledge and Disclosure

For the past year we have noticed more reproductions of antique-cut diamonds on the market. Unfortunately in many instances they are being sold as “genuine old-mine” and European-cut diamonds without disclosure. The proliferation of these goods is fueling the production of antique reproduction jewelry which – again in many cases – is not being disclosed as such.

The reproduction diamonds originate from India and other cutting centers. Usually they are sold in mixed parcels. They include crudely fashioned cushion-cuts and ovals weighing between 0.01 carat to 0.75 carat. The diamonds are cut for maximum weight retention, not beauty and attractive symmetry.

One of the key factors in distinguishing the reproduction antique-cut diamonds from the original lies in the girdle. The reproduction diamonds possess a thick, faceted girdle, whereas the original usually has a thin, often knife-edged frosted girdle.

Although many of these diamonds and jewelry reproductions are perfectly acceptable substitutes for the original antique articles, jewelers should be aware these reproductions exist and should ask suppliers if they are reproductions. Learn to recognize the difference and to inform your clients.

The Goldstein Diamond Price Guide and Market Report is now available by request. It contains current asking prices for European, old-mine cut, briolette and rose-cut diamonds ranging from 0.01ct.to 3.00cts. The price guide also contains information to assist jewelers, designers, appraisers, auctioneers, pawnbrokers, the insurance industry in the purchase, replacement and appraising of older cut diamonds.
