A diamond's certification is sometimes referred to as your optional 5th C. Certification can add value to your diamond as it is your official record and proof of your diamond's quality, as it should confirm what grade your diamond has been given for the other factors (such as colour and clarity).
This can be important to have for insurance purposes and for your general peace of mind. It is also your guarantee of quality, as usually only the best quality diamonds have been certificated by a gemmological institute. It confirms that the diamond is genuine, and each certificate has a unique identification number linking the stone back to the laboratory.
On a certified diamond, this number will also have usually been added by laser onto the girdle of the diamond using an exceptionally fine, non-invasive laser beam. This will only be visible under very high magnification. At H.Samuel, The Forever Diamond is our range of certificated diamonds, and the larger diamonds used in this range have been independently certificated by IGI for your guarantee of quality and beauty.
