Sizing

Rings

The majority of our rings are one-of-a-kind. If you would like to order a ring in a specific size, please contact us and we will do our best to accommodate your request.

Helping you find the perfect fit is our priority. There is a flat fee of $60 to size down. The sizing-up cost varies based on width of the ring and the amount of material required.

Keep in mind that finger sizes fluctuate due to factors such as temperature and time of day. Rings with an open space under the mounting, as well as contour bands, may fit differently than fully round rings.

Ring sizings take 3 weeks before they ship.
