In addition to information about the 4 C’s, an HRD report will include details on fluorescence, girdle size, culet, table width and finish grade. While Carat weight is important, the other C’s (Cut, Color and Clarity) play a larger role in the diamond’s overall beauty. The HRD grades Clarity on the following scale:Ĭarat, which indicates the weight of a diamond-not its size-is measured and reported on an HRD certificate.Ĭarat weight measurements are standard across all grading entities.

GCAL VS IGI FULL
HRD provides a full report, evaluating each diamond on various qualities and components. This allows for significant profits to be made by diamond companies. HRD graded diamonds are usually priced much higher than equivalent diamonds graded by the GIA. They usually average about two Color and/or Clarity grades above the GIA’s grading. Over the years, we’ve experienced incredible inconsistency with HRD grading. Not generally regarded as a legitimate alternative in the United States, HRD still claims to be the authority for diamond grading in the world. HRD is headquartered in Antwerp, Belgium and its chief shareholder is the Antwerp World Diamond Centre (AWDC). History of HRDįounded in 1973 as Hoge Raad voor Diamant, HRD issues certificates for diamonds and gemstones primarily in Europe.

James Allen offers free overseas shipping and great conditions for overseas buyers. Even if you have to pay VAT, the price you’ll pay locally already has that incorporated into the price anyway. In almost every case, you’ll receive more value by purchasing a diamond certified by GIA or AGS from the United States and having it sent to you. If you’re located in Europe and are considering buying a diamond that is certified by HRD, we suggest reconsidering.
