A diamond certificate means that all elements of the diamond you purchased have been examined and rigorously tested. Your certification report is recognised proof of "The Four Cs"--Cut, Clarity, Colour and Carat weight-- of your diamond/s. (For more information on "The Four C's" click here.)
Your report will most likely be from IGI or GIA. All the certification companies we use are independent bodies which test, grade and certify your diamond through their specialist examination processes. We also use HRD, AnchorCert and IGS, but we never use EGL certificates (not recommended).
To receive a diamond certificate at least one of the diamonds in the ring must weigh 0.25ct+ and be graded G colour or better. Alternatively if you choose diamond colour grades H or I, at least one diamond must weigh 0.30ct+. If you purchase for example a 15 stone eternity ring where each stone is small, you will not receive a diamond certificate. This is standard across the industry as diamonds of this size are never certified individually.
Stones weighing less than 0.25ct will not be certified but will be accompanied by a signed valuation document as confirmation of the quality of the diamond. This is standard practice throughout the industry, in fact, some companies don't certify any stones under 0.33ct. The valuation document that you will receive if your stone is not certified, is your assurance that what you are purchasing is genuine and exactly as described on our website.
