Diamond Certificate
Close OR Esc Key
A diamond certificate is an overall report of all the important characteristics of the diamond being examined by independent gemologist / laboratory.

The purpose of a certificate is to help a layman understand the complex diamond specification in a simpler format and able to compare the same with other qualities.

At DiamondsnDiamonds we follow a strict certification program as mentioned below.

Diamonds above 0.30 ct.wt. are certified by GIA/ IGI / HRD / EGL, any one of these internationally recognized independent laboratories. Multi stone jewellery is certified by our in-house GIA certified gemologist known as DiamondsnDiamonds certificate and if requested can also be certified by anyone of these independent Labs EGL / IGI / DGLA. Multi Stone Jewellery can only be certified by EGL / IGI / DGLA as other labs don't offer jewellery certification. This is a standard practice throughout the industry; in fact many jewellers don't provide any certificate for multi stone jewellery.

If you have any queries please feel to call us on 0800 048 0178 for more details.

In the UK, sizes are measured by alphabetical letter A - Z although it is often necessary to go above size Z by appending ' Z+1, Z+2, Z+3,' etc. The sizes are evenly spaced with half sizes.

The American sizes are based on numbers 1 - 15, with half sizes and quarter sizes (eg. 6.5, 8.25). One half size in US is roughly equivalent to one whole size UK.

The European (EU) sizes are based on the inner circumferential measurement of the ring in millimetres.
