Ring Sizing is available for rings distributed by M&S Turquoise when purchased by a registered distributer. Typically rings can be size up 0-3 sizes and down 0-3 sizes. Each ring is individually sized by one of our well trained silver-smiths. We are known for a quick turn around; however, a ring sizing can take up to 2 weeks or more depending on the demand. If you have any questions or concerns feel free to contact us.
