Japanese Koi Ring — Solid .925 Sterling Silver Men’s Wide BandSeventeen millimeters of band width. That's how much silver wraps around your finger wide enough that the twin koi have room to swim across the surface with full body scale detail and flared fins.

Approximately 12 grams of solid . 925 sterling silver, with oxidized grooves
