    CERTIFICATE

At Diamonds Factory confidence and credibility is important to us, and our 50,000+ loyal customers seem to agree, therefore we provide diamond certification for every diamond that we sell.

A diamond certification is an impartial summary of the authenticity of a diamond and the specifications such as carat, clarity and cut etc, carried out by expert gemologists or diamond laboratories. This document is important as it provides the buyer with reassurance that the diamond is as described by the seller.

Keep your document in a safe place as this provides security in the case of loss, trade or resale. Whenever the diamond may leave your possession (for example, to be cleaned) it is a good idea to remind the party taking possession of the diamond that you have a certificate. This should remove any temptation of third-party fraud.

Diamonds Factory: Free of charge and issued by our in-house gemologist. This certificate displays carat weight, colour, clarity of the diamonds, design number and diamond shapes (multi-stone options).

EGL - (European Gemological Laboratory) A third party option who are one of the few laboratories to group grade jewellery products, for example, our multi-stone products such as Tennis bracelets and Eternity Rings.

IGI (International Gemological Institute) and GIA (Gemological Institute of America) - World-renowned independent labs who are considered to be the strictest in the industry. Certificates will display carat weight, colour, clarity, diamond shape, cut, polish, symmetry, fluorescence levels, types of inclusions and certificate number.

 

Keep your certificate in a safe place. It provides invaluable security in the case of loss (helping to establish the quality and size of diamond required for equitable replacement), trade, or resale. Whenever the diamond must leave your possession (for example, to be cleaned), always let the party taking possession know you have a certificate. Knowing you can positively identify your diamond removes any temptation on the part of the third party to commit fraud (such as switching the diamond for one of lower quality).
