Hi all,
This is my first post, but I love reading the forum. I put a deposit on a round brilliant diamond engagement ring, so I haven't paid for it yet. I can still back out. I wanted to get the forum's opinion on the diameter and proportions of the diamond. The proportions are from the GIA certificate. I haven't seen the diamond in person, yet. Hence the reason I did not buy it. I'm only reserving it, because its in the workshop.
Its a 0.76 carat E color VS2
The proportions are as follows:
Measurments - 5.79 - 5.83 - 3.61
Cut Grade - Excellent
Polish Grade - Excellent
Symmetry - Excellent
Fluorescence - None
Clarity Characteristics - Cloud, Crystal
Table - 58%
Crown Angle - 35.5
Pavilion Angle - 41.0
Depth - 62.1
Cutlet - None
Girdle - Medium to Slightly Thick, faceted
The weight ratio is 1.078 or 1.08. Which is technically Excellent cut by GIA, very good starts at 1.09. So you can see its barely there. It should be between 1.0 and 1.05. If the weight ratio was 1.03 the diameter would be 5.9 mm for a 0.76 carat diamond.
My concern is that for a 0.76 carat diamond the diameter should be 5.9mm , but my diamond has an average diameter of 5.81. So I'm afraid it will look smaller than 0.76 carat. I have some GIA calculations to back up my concern if you're interested. Is it possible to have a lower diameter to maximize light passage and brilliance. Or do you think the jeweler is trying to make more profit by hiding some of the weight in the depth or somewhere else on the diamond? Or am I being over analytical? hahahaThank you all for your help.
