Hello I am thinking about buying a Diamond Ring off of Ebay. I am curious if first of all anyone has done this before? If the Diamond I am considering is a good deal? And the certificate authenticity? I guess to start off here are the diamond specs:
Weight: 1.31 Carats
Shape and Cut: Round Brilliant Cut
Measurements: 6.90 – 7.08 X 4.34 mm
Proportions
Total Depth: 62.1%
Table Width: 59.0%
Crown Height: 13.5%
Pavillion Depth: 44.0%
Girdle Thickness: Thin to Thick, Faceted
Finish
Polish: Good
Symmetry: Good
Culet: Very Small
Clarity Grade: IF
Graining: Nil
Color Grade: L
Fluorescence: Faint Blue
Comments: Minor details of polish not shown
About the certificate:
It has a circular seal on it that says (in a circle around the picture in the middle) “European Gemological Laboratory” Then underneath the seal it says: “LOS ANGELES” The top says “Diamond Certificate of Quality analysis issued by European Gemological Laboratory, Inc.” There is also a certificate # is there anyway to look it up to see if it is authentic?
The seller is asking for approx $3000 (three thousand dollars). I am wondering is this a good deal and the certificate that I described does that sound like a real certificate. Any help/advice
would be greatly appreciated. If you want to email me if you need more info please use [email protected] Thanks for taking the time to help out someone in need.
