OK....an update from the shopaholic sister trying to help her big brother find a great radiant.....

So I live in Massapequa, NY......the logical thing seemed to be to swing by Good Old Gold, after all it''s only about 2 miles away. So I did. I loved this place! My husband probably wishes I never found it-boy is he in trouble now

So I knew before I went that Jonathan (Rhino) was booked up solid on Saturday, but I had the pleasure of meeting his brother-in-law (?) Charlie. Charlie showed me two radiants in the range that we wanted. I loved one of them, but need some expert interpretation. I have a PM out to Rhino but I guess he is enjoying his days off, so I need you guys!!

Here is the stone that interests me most.
www.goodoldgold.com/radiant_1_51ct_h_vs1.htm

I am somewhat confused at interpreting the information provided on the goldoldgold website. The Brilliance Scope analysis on this radiant looks great - all marks very high. But I am confused by the Gem Advisor virtual model. It seems to conflict with the Brilliance Scope. The virtual model’s ratings don’t look so hot…….light return mono – poor, light return stereo – good-poor, fisheye – poor. How can the light return be on the poor side when the Brilliance Scope says very high? Sorry if the question is ignorant, maybe they are not quite measuring the same things.

Also, on the sarin report, can someone comment on the crown height and pavilion depth. The crown height is 9.8….not the best from what I have learned. Also, the pavilion depth is 51%....I think this is well over the desired range.

I may be a bad judge of diamonds, but even with what I think would be a few aspects with not such great numbers, I liked this stone. Is this just a case of sometimes you can’t just rely on the pure numbers…..that a diamond with all the right ranges can just be a dud, and vice versa?

Another interesting thing was that I also saw the 1.58 F SI1, and I really couldn’t tell the color apart (from the F to the H). I have had the opportunity to compare and F and an H before and the difference was obvious to me, but not this time.

If anyone could chime in with their opinions I would really appreciate it.

HI LittleSis!
Congrats on the happy news that you're getting a diamond!

I am the wrong guy to answer the specific questions about Gem Advisor virtual model, Brilliance Scope.


But I can tell you that the numbers on the GIA report look very good to me.
You've seen the diamond- from the tone of your post the little guy has won you over- no surprise, a combination of 62 depth and 70 table is going to give you a large looking stone with tons of sparkle.

Anyway- I can also tell you that the price is extremely reasonable- and only bound to get higher.

Hope this helps, and......ENJOY it!

Well... those are different scales. the Bscope uses a special scale for each type of cut. So those Bscope scores compare your diamond with other radiants - the sum total Bscope reds "this is among the nicest radiants in out view".

The GemAdviser uses the same scale for all shapes - so the results read "this radiant is not as XXXX as other cuts, by GemAdviser score". The Gem adviser does not have the marks on the scale to compare each diamond with it's own kind - at least not yet.

Now, it would be nice to have those marks on the Gem Adviser scale. For what I know, ideal rounds reach up to 1.1 (green) scores for light return - and no other shape tops that. Among squares, some of the H&A branded squares get close, but not the radiants and princess cuts. The scale goes up to "Excellent" (red), but no actual result for a GOG diamond goes that far for light return, the only Gem Adviser "excellent" score I ever came across was for contrast and given to a step cut (surprise, surprise

).


Those GOG stones are usually cherries. David (above post) knows it better than I, sure that
