Neal Lane Bridal Set

Hello I have recently upgraded my wedding ring. I purchased my Neal Lane wedding set back in May 2017 at Kay Jewelers. I have maintained my warranty by taking my wedding set to Kay Jewelers every 6 months to get diamonds checked and cleaned. I have not had to replace anything on this set. I paid $5,299.99 for the set. The main ring cost $3,999.99 and the diamond band cost $1,299.99. I am looking to sell it as a set for $3,600 but I am open to sell it individually for the right price.
