This tie tac is done with a Jasper cab. The stone is beautiful. The last pictures show the back. Very nice. The stones are cut with a flat back and actually set in rather deep on the settings. I am very happy with how they turned out. I have made several pairs of a couple different kinds. Take your time looking through them. Very beautiful stones. You are always welcome to contact me as well. Happy to do custom orders of any sort. -- Stop in and visit our e-store for many more great choices.
