How to attach things to leather cuffs?

Hello,


I have a few wide leather cuff bracelets and I would love to know how to attach some interesting trinkets to them.

I have a flat square 3x3 polished stone I would love to attach... Can it be glued into place?

I also have a few vintage pendants I would like to attach - they are sterling silver, one is a cross and the other is a filigree oval.

Any help is much appreciated.

Thanks,
Elaina
