At Arthur Kaplan we are proud of our longstanding diamond heritage and all of our diamonds are accompanied with a valuation certificate that specifies the quality of the diamonds so that you know exactly what you are purchasing.

In addition to our standard valuation of quality, all diamonds from 0.50ct in the Eternal collection are certified by one of the independent and internationally recognized diamond laboratories, the Gemological Institute of America (GIA), the European Gemmological Laboratory (EGL) and the Diamond Institute of Africa (DIA).
