Blue Nile Yellow Gold 14k Floating Diamond 1/3 carat .33 carat

This is my beautiful wedding band (worth $1700) purchased in January of this year. Real diamond and 14k gold and the diamond is 1/3 of a carat. I am upgrading my ring and we want to sell this first. I have the receipt and it is attached in the photos. I am looking for a good home for this ring to go to.
