A diamond certificate is prepared by an independent third party laboratory and verifies that a diamond is genuine, providing an evaluation of a diamond’s characteristics. The certification in recent years has been considered as being ‘The Fifth C’, a factor to determine the value of a Diamond.
A certificate will contain a complete quality description of the diamond and will include information on shape, fluorescence, measurements, proportions and overall finish.
The diamond is verified as being either 100% natural or ‘enhanced’. You would also expect to see the quality of the diamond (carat, colour, clarity, and cut), in the opinion of a qualified and experienced gemmologist.
Perhaps the single most important thing about a diamond certificate is where it comes from. Diamonds must be certified by an independent and well respected gemmological laboratory.
These include: The Gemmological Institute of America (GIA), The International Gemmological Institute (IGI) and Anchor Cert. All of which are used by Rudells.
A diamond certificate is referred to as a report or a diamond analysis document. This would include:
- Shape and dimensions
- Carat weight
- Colour and Clarity grades
- Standard of finish
- Cut grade
The trouble with diamonds is that without a certificate, you only have your eyes to rely on. It is extremely difficult for anyone, who isn’t a qualified gemmologist or diamond grader, to know the exact analysis of the stone by the human eye only. Having a certificate confirms the exact characteristics and properties of the stone.
A Diamond Certificate is NOT the same as a Valuation. A diamond certificate describes and grades the diamond whereas a valuation values the diamond according to current market prices. However, if present, the certificate is used to help appraisers determine the insurance or replacement value of a diamond.
When you buy a certified diamond you’re also buying the certificate, which should stay with the diamond for life. Keep it in a safe place – you’ll need it for the valuation, to either insure or if you were to sell the stone.
