by Dancing Fire » May 12, 2004 machine. I have three different reports from three different machines on the same stone. The one from the manufacture lists the crown angle at 34.4 and PAV at 40.8. the one I recieved from the praiser, his sarin reports has a combination of 34.6 and 41 degree, and then his OGI has it at 34.2 and 40.9 degree.Even the diameter doesn''t match on any of these reports. He says you can scan the same stone three different times and you might get three different readings. The difference is the (HCA scores from 1.1-1.
