Mokume Gane
 

I'm going to Japan in September with my fiance. We're interested in purchasing mokume gane rings. I know you can get them online, but we'd prefer custom made ones from Japan. Is there any place that sells these for a reasonable price? Or is there a place where I could even buy a hunk of sword metal so we could make the rings ourselves?

"mokume gane" means "木目金" ?
 

it looks like Damascus steel.
I have fake Damascus steel knife, but I knew mokume gane rings for the first time.

This shop seems to create the customisation ring.
