I have a very nice all Rose Cut (flat pavilions) diamond ring in my shop
for repair. Anyway at some time in the past 3 of the side stones had
been replaced with more ‘modern’ cut stones. They want it returned to
the original look. I am have trouble finding the diamonds. 2.47mm,
2.43mm, and 2.41 or very slightly larger are my best guess, none were
even close to round, but nor are they oval. Some one in the US must
have something appropriate.
