Most of our rings will initially come in a standard size. Every design then has set guidelines about whether it can be resized and by how many sizes. Online we list the sizes the ring can be resized to, then if needed we arrange complimentary resizing by our manufacturing team before we ship. If your ring is being resized it can take between four (4) to ten (10) business days for your order to be prepped for shipping. Men's Tungsten and Titanium rings cannot be resized. Please check each product page for the size range available to purchase online. If you are purchasing in store the size range and timescales will vary. In-store we can resize ring the sizing guidelines however additional charges will apply.
