Buying couple rings in Tokyo?

My boyfriend and I are heading to Tokyo in about a week and I was wondering where we should look for some nice, decently priced couple rings. Thank you for your time.

You could try Tifanny's in Maronoucvhi. Not too sure about the price though.

Yeah I was looking for a more affordable place. We also have Tiffany's here so I wanted to try something else.

I don't know which area in Tokyo you are staying at, but check out jewelry/accessory sections of department stores in town - Marui (several locations including Shinjuku, Ikebukuro), Lumine mall (Shinjuku), Primtemps (Ginza) would be the ones for younger customers :)
