Over the last ten years, Diamant has come to trust and know three reputable gemological institutes for the diamond certificates we use every day.
GIA (www.gia.edu/)
HRD (www.hrdantwerp.com/)
IGI (www.igiworldwide.com/)
We do not use or recommend any other certificates as in our opinion, they are just not on par with the above grading standards.
There is way more to a diamond than just carat/color/clarity/cut (4Cs) and when you buy a diamond with us, we will explain every fine detail; from angles and percentages of table/crown/pavilion to millimeters spread and depth of your chosen diamond.
Finally, make sure you are given a certificate and not a valuation or appraisal when you buy a diamond ring as these valuations just assign a monetary value to a ring (needed for most insurances) whereby a certificate is an independent scientific review of the diamond.
