10K white gold diamond engagement ring

Past, Present, Future diamond engagement ring. 3 Diamonds on top 6 small diamonds 3 on each side. Purchased at Zales .My son bought this for a girl and thing's didn't go as planned so I'm selling this for him. He paid 999.99 about 10 year's ago so I describe to the best of my knowledge. I know you can return it back to Zales and they will give you the credit of 999.99 on a purchase of 1900. MAKE SENSE? He's moved on married she wants this ring gone!!!
