Hello all,
I'm looking to buy a diamond engagement ring for my significant other (hopefully soon to be fiance)! I've done a good amount of research over the past few weeks on diamond characteristics and have found one through an online vendor that could be a contender, but wanted to ask all you experts here on your opinions.
The diamond I'm looking at is a round brilliant cut. It has a GIA certificate that lists 0.76 carats, E color, VVS1 clarity, and excellent cut. The GIA certificate also lists excellent polish, excellent symmetry, no fluorescence, and mentions "Pinpoint" for the inclusion. The inclusions seems to be 1 small white pinpoint on the crown off to the side (but not on the table), and a 2 smaller pinpoints on the side of the diamond (I think on the pavilion) that you can sort of see through the crown if you turn it the right way (but again not through the table). The vendor has assured me that you can only see them under magnification and that it is eye clean.
I ran the proportions through HCA to get an idea for how good the cut really is, and I got a 0.9 score with excellent light return, fire, and scintillation, and very good spread. The exact proportions are as follows:
56% table
62.1% depth
35.0 crown angle
40.6 pavilion angle
no culet
medium to slightly thick girdle, faceted (4.0%)
15.5% crown height
43.0% pavilion depth
50% star length
75% lower girdle facet length
measurements: 5.81-5.84 x 3.62mm
My questions are as follows. As I understand it HCA assumes medium (1.2%) girdle and symmetric measurements. Does the fact that this diamond has a much thicker girdle (4.0%) than that reference point and is not perfectly round (5.81-5.84mm) impact the cut materially? That is to say, will light return, fire, and scintillation be impacted a lot? Does the fact that the girdle is faceted impact anything either way? What would you guys assume is a reasonable price for a comparable diamond? Lastly, overall do you think that this would be a good purchase for an engagement ring?
Thanks in advance!
