I would to have a personalized ring made for myself. I would like it to have my dad and mom 's birthstone in it. Engraving would be a plus but not necessary.
I know Walmart has a huge selection of personalized rings like that. You can customize it in style, metal, gems, engraving. Maybe start there to get ideas?
I've got limited places here in the sticks of ky. (And money!) I've used jcpennys and they didn't give me the right metal. So I ended up ruining my ring cleaning it and totally can't do anythng about it! Ugh. So DH went to Walmart and got me a new diff family ring at Christmas. I love it and it's perfect like ordered! Just my experience.
just a thought, but you could put two stacking rings together - or bonded stacking rings. There are a lot of people on Etsy who make these. If the band is thick enough, you could engrave it.

this one is kind of large, but serves as an example.
