Diamond Certification
The DCLA Diamond Certificate is a comprehensive diamond grading report, providing all the information necessary to make an educated diamond purchase.
The DCLA Diamond Certificate guarantees the authenticity of diamonds, and rules out the possibility of a diamond being synthetic or an imitation.
The Diamond Certificate also contains a complete description of the diamond including: a unique ID number, carat weight, colour grade, clarity grade, shape, measurements, proportions, proportion grade, transparency grade, polish grade, symmetry grade, fluorescence, hue and other remarks or characteristics which determine the quality of the diamond.
The individual parameters listed above allow for accurate identification of the diamond, while the overall grade for a set of parameters provides easy understanding of a diamond’s quality.
All of these diamond quality characteristics determine the value of a diamond, and are discussed in detail under The 5 C'S of diamond grading.
The DCLA Diamond Certificate is the most important document your diamond will ever be linked to. The Diamond Certificate does not date or expire, and provides a steady foundation for calculating the replacement value of your diamond.
To prevent counterfeiting the certificate has various security features including holograms, a UV activated text seal covering the information field, special UV activated paper, and an embossed foiled crest.
DCLA also provides an Online Diamond Grading Report Check, which is your way to verify the authenticity of information for your diamond, should it be required for an insurance appraisal, or to replace a lost or damaged Diamond Certificate.
