Firstly, I am really glad to have found this resource and while I have learned a lot already simply by reading, I''m hoping to get some advice on a couple more specific questions.
I am looking at a number of diamonds at this point, but will make an effort to focus on only one or two at a time, as to not overwhelm you good folks.
First, our criteria: we are looking for a RB, ideal cut diamond in the colorless range (D-F). It may dip as low as SI2 in clarity provided that it is perfectly eye-clean. We would also like to be at or above the 7mm diameter point, which (roughly) translates to 1.25c+. We love fluorescence, but see it purely as a bonus (i.e. I will not turn down and otherwise perfect stone just because it doesn''t exhibit it). Also, our budget (for the stone itself) is a fairly firm $9500.
One of the diamonds I''ve been entertaining is the following:
CANDIDATE #1:
----------------------------------
Report: GIA
Shape: Round
Carat: 1.52
Color: E
Clarity: SI1
Depth: 60.4
Table: 58
Crown Angle: 31.1
Crown %: 12.8
Pavilion Angle: 40.5
Pavilion %: 42.6
Girdle: Medium-Thick-Faceted
Polish: Excellent
Symmetry: Very Good
Culet: Very Small
Fluorescence: Strong Blue
Measurements: 7.35-7.39X4.45
---------------------------------
It scores a 1.9 on the HCA, with "good" light return, "excellent" fire and scintillation, and "very good" spread. The ideal scope shows only minor leakage and the magnified image appears very clean, although I am in the process of confirming this. It also has strong fluor, which might be a bonus.
I guess my main concern is the crown angle. Am I correct in this? Is there anything else I should be wary of? Does this generally look like a good bet or am I better off dropping down in size a bit and perfecting the cut?
Thank you in advance for your thoughts and comments!
