Beautiful Diamonique Sterling ring

The shoulders of this ring feature invisible cheek to cheek pave stones. The center stone is emerald cut, or possibly a fancy cut stone. The sparkle is spectacular! North to South, 7mm, looked like approximately 1 ct. No guess as to total equivalent weight. Size, approximately 7.25. The band does show that it's pre-owned, but no one will see that! It is sterling bonded with platinum. I am actually cleaning out my own closet, so make me a reasonable offer!
