UNN THICK is a one cm wide solid silver ring and every one of them are unique. The inspiration to this ring came from seafoam and its silvery bubbles. And since silver foam transforms into golden by sunset the foam is also available in18k gold. The ring on the picture has a closed back but the ones I'm selling comes with an opened back. That means that you just have to estimate your ring size to get ut right. Handmade in sterling silver.
