Greetings!
Has anyone had luck using a microscope reticle to measure a diamond's crown angle?
Or, do you know of any other special methods or tricks for measuring angles?
Thank you and best wishes,
Katy B

I have a loupe reticle that I used to use occasionally. Not for crown angles though, for mm measurement.
I'm sure with a little practice one could get reliable results for crown angles.
If I need to determine a crown angle, especially of a mounted diamond, I use the optical method Glenn Lovelady describes here.
