Carbon ring with a concave sterling silver inlay. The diameter of the upper edge is approximately 33 mm. The ring is also available in other alloys upon request. It is available in ring sizes from 50 to 70 mm inner circumference. Larger or smaller rings are available as custom orders. Don't know your ring size? No problem: Upon request, I will send you a ring sizer after receiving your payment, which you can keep (free of charge within Germany - for international shipments, the shipping fee for the ring sizer will be retained if you subsequently return the ring). Furthermore, you have the opportunity to try on the chosen piece during the return period. This way, you can easily return the ring if it doesn't fit perfectly. I will then send you the same piece in the correct ring size as quickly as possible (free of charge within Germany if you subsequently purchase the ring).
