Hi There,

I have never been able to find the formula / rules for what size diamonds can be flush set into what thickness of metal and hope someone here might be able to help

For example:
If I have 1.5 mm thick sheet, what would be the max diameter of diamond that could be flush set comfortably without poking out the other side? is there a formula or general rule that I can use to work it out that can be applied to all sizes and thicknesses?

Thanks for any guidance!
