#3 is safest from the number, but #2 could work too. #1 probably will have significant obstruction issue, might not be good for a ring stone. Idealscope image will tell more so request for one, JA allows for 3 request.

shallow pavilion angle can cause obstruction issue.

Pavilion angle is too shallow. If it has obstruction issues, the black, which simulates the observer's head, in the idealscope will be more significant, not just limited to the arrow-shafts.
