Welcome to Midwest Treasures KC! We do combine shipping. After purchases are made, and paid for, we refund excess shipping when shipping occurs. Please see pics for details as they are better than what I can describe. Size and length are in the title. New condition rings are available in other sizes. Contact us for a request. Please keep in mind that sterling silver items do tarnish and pre owned items will have tarnish. All items are cleaned. Some will have a natural patina from use and age. See pictures. Please send offers through the offer system. We do not negotiate through messenger. We ship on Monday/Wednesday/Friday. Orders submitted by noon on shipment days will ship same day. Please save us as a seller and checkout my store. We list 100-200 new items every week. If you have any questions or concerns, please reach out before leaving feedback. We want you to be happy!
