ONT face="Papyrus">We always discuss on here about how AGS 000 is not the end-all-to-be-all when you are searching for stones. When I was learning..I didn't really understand how the AGS000 grade didn't mean a great stone. Wasn't it supposed to be easy for you to find a great stone if you didn't know anything? Didn't the AGS000 grade mean that hands-down, that stone would be 'ideal'? Kind of like 'Diamonds for Dummies' (which I now think SuperbCert and ACA stones are...but I'd probably buy one cuz they sure do look pretty!). Like the Macintosh of diamonds?I'm a PC girl myself.
Anyway--I was checking out a website online today that was recommended to me as local and I found out they use the virtcert engine that alot of other vendors do. For fun I was researching 1.50c+ stones and clicking on the ones that had Sarin results and punching them into the HCA (yes its Friday afternoon and I am very bored).
I was surprised to find that many of the 'ideal' AGS000 stones scored very badly on the HCA. Well not BADLY in all cases..more like..not quite 'excellent'. Well not *surprised* that there are AGS000 stones that score badly on HCA--but rather that so many of the stones that actually HAD Sarins for them on this site, had non-desirable results. Then I thought...what a great education tool!
So for those people who want to know about AGS000 or want to see a mediocre cut, but expensive stone...view the following.
64.4 depth AGS 000 ideal G VS2 (ha ha 64.4% depth!)
4.8 on HCA Good/Good/Good/Good scoring
2.4 HCA scoring, all VG --- AGS 000 according to Sarin (not too bad!)
4.8 HCA scoring, 2 VG, 2 Fair--AGS 000 according to Sarin (yikes!)
2.2/2.7 HCA scoring (accounting for diff table sizes on Sarin vs report), AGS 1 according to Sarin (better HCA than AGS all of the AG000 above? interesting.)
For those interested..my stone is an AGS7 due to the large table and shallow depth...it scores a 2.3/2.8 on the HCA depending on what day you punch it in (that Garry...always making changes!!). When I bought it, it scored a 1.5 on the HCA, but since then the criteria have shifted. It's a gorgeous stone and looks better than all the diamonds I have compared it to since we got it. (of course I am a little biased) When Lugus comes into town someday, I am comparing it to his sweetie's SC stone.
Anyway--just goes to show that the AGS000 grade does not always make the stone. For those of you searching, be sure to use all the tools available BESIDES the certification, because that does not guarantee anything except color and clarity and ctw...and sometimes not even that!
