This tri-colored ring is available here as standard in carbon, silver, and 14-karat yellow gold. The ring is 4.8 mm wide and 2.2 mm thick. It is also available as a custom order in other variations. Only currently in-stock items can be ordered through the online shop. Of course, I can also supply the ring in all other sizes. 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 the ring is subsequently exchanged). 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).
