Need Advice for making DIY Rings from my collection

I’ve recently gotten into jewelry and had the idea to turn my GoGo Crazy Bones and die collection into custom rings I can mix and match. I thought it’d be a fun way to make my accessories more personal.

I started researching how to actually make the rings, but as a complete beginner, most of what I found was pretty overwhelming—lots of tools, techniques, and costs I wasn’t expecting.

So I wanted to ask this community: what are some easier, beginner-friendly ways to make custom rings like this without spending a ton of money? Any tips, materials, or advice would be super helpful. Thanks!
