HRD Certification Question - Apples &/or Oranges?

Rob D Cradle Rough Rock Total Posts: 3 Last Post: 3/27/2003 Member Since: 3/23/2003	I have enjoyed reading this forum as a lurker for quite some time, and I appreciate everyone's input. Now, however, my time to make a decision approaches, and so I propose, hehe, this question: I have viewed a HRD certification emailed to me with the following information: 2.19 carats; Clarity SV2; Color rare white (G); fluor - nil; girdle 2.5% (I think - this was blurry); culet pointed; table width - 60%; crown height 15%; pavilion depth, 43.6%; finish very good, proportion very good. (I have been advised by the merchant that the depth percentage is 61%) My questions are these: If pavilion angle and crown angle are so important, how have the Europeans made due without same? Is it possible to extrapolate brilliance and fire, et cetera with only these criteria? Are there any detrimental numbers here? (Although if a majority of you give thumbs up I will send the stone to an appraiser) What would be the internet ball park value for this? I would appreciate anyone's input. Thank you! J

As per the angles... It's better to know at least all the %s than only table and depth (case in point GIA)... Am I wrong? BTW, is it VS 2? _____________ Omnia Mea Mecum Porto. Giangi

The HRD is the diamond grading laboratory for the Belgium High Diamond Council with a location in Antwerp and one in Canada. We still advise obtaining a Sarin / OGI computerized proportions analysis which will provide you with the crown and pavilion angles rather than the percentages provided on the HRD diamond grading report (not a certification) because the angles are a more accurate indication than the percentages...

Rob D Cradle Rough Rock Total Posts: 3 Last Post: 3/27/2003 Member Since: 3/23/2003	Thanks for the response Giangi and Niceice! (Sorry, I have been away to the funeral of the grandmother of the object of my affaction, which turned out to be a celebration of the remarkable life of the lady.) But I return happy at the response of you two! Yes Giangi, you are right on all counts as to your presumptions as to the other info on the HRD report. Pav depth 43.5%; culet pointed, finish grade very good, girdle 2.5% thin, faceted, crown height 15%; proportions very good. Yes, VS2. The merchant now indicates that they believe the crown angle to be 35 1/2 degrees and table 60%. I am ready to send this to an appraiser for evaluation, but does this sound like something that would look bright and somewhat near ideal proportions? What would something like this be worth, and, more importantly, what do you think it would look like when the appraiser views the stone? I have put info in pricescope but I don't know if the information that I have would give me an accurate analysis before the appraiser stage. I have been quoted a price, I just want to know if it is in the ballpark of non B&M prices. Again thanks for your help! J

BTW, the diamond gets only a 5.2 on the HCA, but I've seen many stones with similar proportions and they looked all very nice... Let your eyes decide... The stone isn't an ideal cut, but nevertheless it's nicely proportioned and should be quite bright... Is it from an internet vendor? _____________ Omnia Mea Mecum Porto. Giangi

Rob D Cradle Rough Rock Total Posts: 3 Last Post: 3/27/2003 Member Since: 3/23/2003	Giangi, it is not from an internet vendor. I just need to know others' opinions of how promising the stone looks considering the facts that I have now. Hopefully an appraiser may chime in and give an educated guess. I will be looking at another stone and I want to send only one to an appraiser at a time. I appreciate the response. J

Phobia Rough Rock Total Posts: 1 Last Post: 12/3/2005 Member Since: 12/3/2005	hi there, As an HRD certified grader, I'd like to tell you the easy way to decide about a cut, in HRD they do it by precentage not by angels, and use the proportion scope to identify these percetages, then they decide whatever it is, it's not raccist guys, but HRD is the oldest and most proffesional ever, and also they have a cretirea which is a lot diffrent than Americans yassin
