The ring on the left is a simple platinum wedding band with a glossy plain finish. This is a very popular style in Japan. It is especially popular with men who wear suits to work every day. A crisp suit and a simple platinum wedding band gives a very nice formal look.
The ring on the right is a hammered wedding band made of pink gold with a pockmarked pattern that reflects light diffusely and glistens.
The combination of hammered and pink gold is very popular with MITUBACI's female customers, and the 2.0mm wide ring looks lovely stacked with your existing slim fashion rings.
