Ok-Here' my inquiries to the cut geeks..lol
I am interested in the following stone:
Stone: Round Brilliant AGS "0" Hearts & Arrows Diamond
Weight:.451 ct.
Depth Percentage: 60
Table Percentage: 57
Girdle Percentage: 1.0-1.4
Crown angle:34.8
Pavillion Angle:40.7
Dimensions:4.98-5.01*3
HCA Results in 4 excellents across the board based on posted sarin data. With an Overall score of (1) for total visual performance.
I like to use 3 things in evaluating a stone:
1.HCA - Based on Sarin Data or Mega Scope Readings (which measure the precision of cut.
2.B-Scope - Measuring the level of Brilliance, Fire, & Scintillation in a stone.
3. Like to take a peak at the Firescope to see How much leakage a stone has.
With all these things in mind consumers can get a great insight into how well a stone might perform. Of course the last determing factor is seeing the stone and being pleased with it.
My question is that I am aware that most sights have initial Sarin Data so plugging numbers into the HCA is easy. There are few sights that have B-scope Date and imaging to test leakage. (Good Old Gold & SuperBCert) For discriminating consumers like myself who like to have a good balance between the 3. What can a consumer expect from stones which might score high on the HCA in circumstances where B-scope readings and imaging to show leakage is not available.
I know there is a plethera of professionals on this sight so I want to hear you opinions. I am well aware that each stone has it's own characteristics & there is not a finite answer, but my main question is on the average how well to stones which rate high on the HCA rate on the B-scope. I know you guys have seen lots of stones come across yoour peering eyes so I want to hear everyones opinions.
Thanks in Advance-
