Im curious to know if you see a difference in craftsmanship
Pretty rings!
I think the only way to compare craftsmanship is to look at something the same that they’ve made. So for example, Leon M is world famous for his tiny pave setting & David Klass for his top notch engraving. Two amazing craftsmen with different skills.
So it’s hard to compare two different rings really? Can you see differences that make you question the quality of the rings? Personally I like the look of the right ring. The design is more unique, but I can’t vouch for quality from your picture.
