An unusual style and signed with an Osby Barton marking this special piece is a conversation starter for sure. The oblong faceted pink stone is a saturated color and securely set in the yellow gold band. Inside it is marked with the initials OB and a maltese cross. Along those markings it also says 10k for the gold content. If you look at the extreme close up you can see there is a tiny chip on the long side of the pink stone.
