1.2k center stone with 10 more diamonds

I let my x pick out her own engagement ring, and she picked out this ring. I had a m.v.a. and was left a paraplegic and she didn't stick around. So now it is up for grabs. It's a beautiful antique ring that ANY lady would be proud to wear. It has a 1.2kt center stone, in 18k gold, with 5 more diamonds on each side of the center stone, all set in that grand antique style that they are trying to reproduce to day. But this is a REAL antique. I have had it appraised two times, and the lowest appraisal was for 5 grand.
