The 4 C's of diamond valuation

Each diamond has different characteristics. To evaluate them, the gemmologist studies the diamond according to 4 predefined criteria. These evaluation criteria are used by all gemologists worldwide.

The buy-back price of a diamond will therefore depend on these 4Cs:

  1. Diamond weight is defined in carats. One carat is equivalent to 0.2 grams. The greater the weight, the greater the carat, and the more expensive the diamond.
  2. The diamond cut, which corresponds to the jeweler's cut made on the rough diamond. The cutter gives the diamond precise geometries to enhance its brilliance. The diamond's brilliance depends enormously on the quality of the cut, and therefore on the proportion, polish and symmetry that influence light reflection.
  3. The purity of a diamond is determined by the inclusions present in the stone.
  4. Diamond color ranges from white to yellow, classified by letter from D to Z. The whiter the diamond, the higher its purchase price.

Diamond buy-back price

The price of a cut diamond is based on the Rapaport Diamond Report, a list of international diamond prices. The Rapaport is used as a reference base to establish the price of diamonds sold individually. This list is issued every Friday, but the price does not change automatically from one Friday to the next. As the diamond prices published by the Rapaport are in dollars, the price is converted into euros at the time of appraisal.

Appraising a diamond before buying it back

Appraisal is the process of determining the origin and quality of gemstones. A gemmologist trained by a recognized laboratory and possessing the necessary know-how will be able toappraise your stone. During the appraisal, he determines the diamond's market value according to the 4 criteria known as the 4Cs seen above. In most cases, we offer a diamond buy-back price immediately after the appraisal.

If a diamond needs to be appraised in greater detail, an external expert from one of the world's leading laboratories, such as GIA, HRD or IGI, equipped with the latest technology, will be dispatched to appraise your stone with greater precision.
