Thorsten is a cutting- edge designer specializing in wedding bands for both men and women. Their over 400,000 unique designs are all made with high quality alternative metals (such as Tungsten, Titanium, and Ceramic) or traditional metals (such as Gold, Silver, and Platinum). Each ring comes with a Lifetime Warranty. This means if your ring cracks or breaks from accidental damage, it will be replaced under warranty at no additional charge! In addition, due to the hardness of alternative metals, they cannot be re-sized like traditional gold or platinum rings. Therefore, if your finger size changes, the ring will be replaced with a different size at no additional charge!
