Certified Diamond – Qualitative and Quantitative variables that should be on your certificate

Once you’ve chosen your diamond and given time and consideration to its cut, colour, clarity and carat, how can you be sure the diamond you’re getting is of the standard you believe it to be.

One way to guarantee its value is to receive an independent Gemmological Laboratory Diamond Certificate.

This certificate ensures that the characteristics contained in it match your diamond and have been determined by experienced diamond graders using recognised gemmological instruments and expertise.

Those minute characteristics, invisible to the naked eye, which we learned about in Clarity, have a major bearing on value. Your independent certificate guarantees your diamond’s grading.

The certificate is a diamond grading report describing objective factors, both qualitative and quantitative, and an almost infinite combination of all of the variables, based on the measurements (diameter, height or thickness, minimum and maximum diameter with the girdle) and physical properties which define each stone:

Cut, Colour, Clarity & Carat.

Any defect of the stone structure must be noted on the certificate, example: possible trace of laser drilling or rough trace.

The certificate number on the diamond’s girdle should match the number on the certificate. Click here to read more about the main gemmological laboratories in the world.
