Hello all,
I've been shopping for a 1ct stone for a little while now, learning everything I can. I recently started using HCA to help evaluate potential purchases. I saw this stone recently (in person)...
GIA Report
Round Brilliant
Size: 1.03ct
6.45 - 6.49 x 4.00 mm
Color: H
Clarity: I1
Cut: Excellent
Polish: Excellent
Symmetry: Excellent
Culet: None
Fluorescence: None
Girdle: THN to STK, F (3.5%)
Table: 57%
Depth: 61.9%
Crown Angle: 34.5 deg
Pavilion Angle: 41.0 deg
Star Length: 55%
Lower Half: 75%
The above specs give the following HCA output (assuming I'm using it correctly
):
Light Return - Excellent
Fire - Very Good
Scintillation - Very Good
Spread or diameter for weight - Very Good
Total Visual Performance 1.9 - Excellent
I've uploaded the reference diagram showing the inclusions. The main offender on the left (which I had a hard time seeing, for what it's worth) would be mostly covered by a setting prong.
So now, the price...$4,500. Would I be totally out of line by saying this is a really good deal? Any input is appreciated. Thanks.
