"Quality: gold 2.76g standard drill 0.224ct" It is estimated that there is something wrong with sentence break when typing. See if this "standard" refers to gold 2.76g or diamond 0.224ct, which is estimated to be the weight of the diamond. The inlaid diamond cannot be accurately weighed.
"Mosaic material: Pt950 (standard)" does not represent the test result.
Basically, this certificate can only prove that the diamonds tested are real, and nothing else can be proved.
