3 stone emerald cut diamond ring/engagement ring in Phoenix, Arizona For Sale

I have a BRAND NEW, never been worn 3 stone emerald cut diamond ring I purchased for my ex and never proposed to her. Long story short we separated and I can no longer return the ring. I have a ring certificate and a few pics you can look at. Serious inquires only, please. I paid a little over $7,000 for the ring and I need to get as much as possible out of it. Please be considerate on offers if any, I' am already taking a huge loss on it. I just want it out of my life. Looking for cash, but could settle for a decent trade!
