Size 5.5 The engagement didn't go through and I don't plan on giving it to someone else. They were purchased for Kay Jewelers. Ring come with an extended service plan. You will have to get them inspected every 6 months to keep the plan in going. If anything happens to the diamonds Kay will replace them free of charge.That is for life. All 3 rings come together. If you have any questions please feel free to ask. Location: Albuquerque it's NOT ok to contact this poster with services or other commercial interests newmexico
