I made this at home for my partner who loves chunky rings lol.
Size 7.5, 16 x 1.6mm band.
I cut the amethyst using a small diamond cutting disc on a cheap rotary tool.
I didn't have a ring mandrel at the time, so the ring was formed around a socket from my tool box that just happened to be the right size for her.
I used 0.5mm sterling flat wire as the bezel, which turned out to be way too difficult to set over the crystal's faces. If I do it again I'll use fine silver instead.
