Diamond certificates: an IGI or GIA report with every main diamond.
Every main diamond comes with an IGI or GIA grading report. The report describes one stone.
What a report lists.
A grading report is written by an independent laboratory about one stone. It does not describe the ring or the brand, and it gives no price.
- The report number and the date.
- The shape and cutting style.
- The measurements in millimetres and the carat weight.
- The colour and clarity grades, where the laboratory grades them.
- The cut grade where the laboratory grades the shape, with polish and symmetry.
- Fluorescence and the laboratory's comments, including any note about treatment.
- Whether the stone is natural or lab grown.
How to read it.
Start at the top with the report number and the shape. Then read the measurements and the carat weight: carat is weight, not size, so the millimetres show how the stone will sit on your hand.
Next come colour and clarity, then cut, polish and symmetry. Not every report gives an overall cut grade for every shape. For an oval or a pear, polish and symmetry describe the finish. Fluorescence and the comments come last.
Each line is explained in our guides to IGI reports and GIA reports.
It comes with your ring.
Every main diamond comes with an IGI or GIA report. Your ring arrives in special Mazimo packaging with a certificate folder and the invoice.
A diamond ring has two kinds of document. The report describes the diamond. A Mazimo certificate of purity describes the 18K gold.
IGI and GIA.
IGI and GIA are two independent laboratories, each with its own reports. IGI issues most of the reports that come with lab grown diamonds and grades natural diamonds too. GIA is the benchmark much of the trade uses for natural diamonds.
Ask the team which of the two comes with the diamond you are choosing.
