Guess the size of the Bullet cuts on this vintage Cartier 3 stone

You can see if those sides were set at a less steep angle, they would face up longer.

This is good. I took a screenshot, blew it up to fit most of the screen, and used a transparent mm rule held up to the monitor. That's what I do for all of these things. It is very accurate, assuming that the original photo is sharp. As mentioned, need to account for relative closeness to the lens but the side-shot helps a lot.

Impressed that they are aware of the "ethical" provenance from the '50s -- that's a long chain of custody.

Great to know, thank you! I’ll have to get me a transparent mm rule

A cheap plastic protractor could be used to measure the angle.
