Pandora Heart (Promise) Ring

My ex got this for me, and I kept it in great condition! I had it for about 6 months. He cheated on me and now I’m looking to get rid of it. It was $500, but since it’s been worn i’m asking $350. This is totally negotiable though!!! I honestly just want it gone. I’ll send the box out with it too! 14k gold (all the way through, not just plated.) Cubic Zirconia Size 8
