Uncertainty of your ring size is not unusual. We will provide you with our complimentary ring size gauge. If you are intending to purchase a Mokume Gane or Royal Mokume Jewelry© ring, we will send you the ring size gauge to ensure the perfect fit. Unlike most jewelers, we also use the bottom or leading edge of the ring to measure and determine the size. If you have any question related to ring size, don’t hesitate to email us at email@example.com or call us at +81 (0) 80 3835 7123.
