 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 item). Furthermore, you have the option of trying on the chosen piece during the return period – if the size doesn't fit, simply return it and I will send you the correct size as soon as possible (free of charge within Germany if you subsequently purchase the ring).
