It is normal for the designs in the SSC to have angles listed in decimal to two decimal places. This is a result of the computer designs having this capability. You are expected to interpolate on your faceting machine to best approach this angle and cut all the facets in a tier to that consistent angle. If you do this well, the result will be a stone that will be judged based on the parameters in the judging manual. There is no means for the judge to measure angles to 1/100ths of a degree.
Hi, Ron. There seems to be a discrepancy between the design in the newsletter and the one on the website. I think the website version is correct (no fractional indexes). Click on “Competition” in the menu. No login required.
