answer:i don’t know if you’ll be able to find anything that cheap in the city. Most shops in SF need to charge more because they’re located in a pricey area. If you got this ring made by a local artist, do you think they would be able to resize it for a small price? If they can’t/won’t do it, I would then suggest finding an art student in SF (there are tons) who could do it cheaply. I have a couple of friends who just graduated from the Academy of Art University and through them I know that there are lots of students focusing in Jewelery art.
