Heart shaped diamond solitaire .57ct 14kt size 5.5

I just recently purchased this, on behalf of my daughter. The diamond is gorgeous, and the ring is lovely, but it won't work with the semi mount that she has n mind.
The ring is stamped 14kt .57 and is a magic glo brand.
The prongs do have a few nicks in them, but overall, the ring is in great shape, a very pretty, classic ring!
