What does it say about a stone if the the symmetry grades in all categories on the stone's sarin report are 0? I know that there was recently a gigantic thread about AGS grading, but what does this mean about a stone's proportions?
Neil, the premise of the long thread acbutk points to is that there ARE new charts from AGS...and these have been used to plot the points in the current HCA tool.Date: 3/1/2007 7:14:13 PM
... and then ranks this value using the old AGS grading scale.
The biggest single difference between the new system and the old is that the various parameters don’t stand alone in the new approach. Certain combinations of attributes will now score better (or worse) than the individual ones would have ranked in the old system.
I have no idea how the backend of the ‘search by cut’ db here works. My guess is that dealer simply includes extra fields in each record to indicate cut rank, H&A, etc. and that there is not an automatic credibility check built in for this. Perhaps the admin or one of the dealers can answer where this data comes from. Is the AGS score calculated or entered by the dealer?
