What does ‘Certified’ mean?

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.

Who certifies the Diamonds?

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.



What is included within Diamond Certificate?

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

Why does a Diamond have to be Certified?

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.

Will I need to have a valuation completed if I have a Diamond Certificate?

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.
