There is probably no way for you to remove the stone without chipping the stone. You would be best to take it to a jeweler and have it removed. If the stone was prong mounted, you might have a chance, but I would think that the stone is mounted in a very solid mount. Being a mans ring, it is probably crimped in, which requires that the stone actually be cut or ground out of the ring with a burr or a jewelers saw.
