auroraorangey Rough Rock Total Posts: 24 Last Post: 11/14/2007 Member Since: 10/17/2007	Hi guys, I'm looking at this stone http://www.goodoldgold.com/diamond/3672 The megascope puts its table % at 55.6% thus getting a HCA of 2.1. The helium and AGS cert states the table % as 56.3% and 56.2% repsepctively, getting a 1.3 and 1.4 on HCA respectively. I can understand the limtations of technology, so it's alright for helium and AGS cert to have slightly different measurements. But the megascope's measurement is worrying me. The HCA score is not as pretty. Pls help!

I read that megascope and sarin are more accurate as compared to the rest? If that's the case, AGS cert and Helium has abt the same numbers. Does it mean the cert isn't as accurate? Perplexing!

AGS use sarin typically. Also...2.1 not so bad, anyway. Anyway, regardless of the imputed measures...the 0 for light performance trumps the HCA calculation largely, also.

If you dont mind the L color its one kicken stone. ........... Karl has joined the diamond trade and is now posting as Karl_K
