Wedding ring

I need to sell this ring. Purchased in December 2017. I have the receipts from Kay Jewelers where I bought it. It was sized to 6 3/4. Total price for the diamond ring and the 2 bands that go with it was $2081.10. I would like $1500 but I’m open to offers. If you take this to Kay Jewelers, they will let you trade it in for a value of $2081.10 as long as you spend another $2081.10. So you would leave with a piece of jewelry worth $4162.20 and only have to pay whatever you buy the ring from me for and another $2081.10. It is 10k white gold and I’m not sure about the carat size. Also has black diamonds.
