All jewelry is made to order and ships within 8-10 weeks. All rings are available in sizes 4-10, including half, whole, and quarter sizes. The resizing of rings in orders that have already been fulfilled is not available (i.e. customer wants a different size). If a different size is wanted, a new order must be placed with a minimum of three pieces. A minimum of three pieces of jewelry is required to place a wholesale order. Wholesale sales terms are automatically agreed upon to a 50/50 split. You can reach out directly to Hannah@goodluckhandmade.com with any further questions you may have.
