Square profile silver bands

What’s the story?
These were prototypes of some wedding bands that I was developing for a client.

Details:
The larger is 6mm at the corners with scooped sides and the smaller is a little over 3mm with parallel sides.

Sizes:
Large: Q1/2, and the small is K1/2.

Can they be sized?
A little bit up but down is tricky.

Variations:
The final rings had bands cut into the top surfaces and diamonds in one corner. View these basic rings as a blank canvas, if you like, and let your imagination run wild.
