Perhaps my own analysis in another post, about this. For now, I have a little information to bring to the table. The same fellow used to market it at www.segulahring.com, and while that site is now down, the WayBack Machine has an old copy of at least the front page. The testimonials, and so on, are unfortunately not there.
Here is what they had on their main page. I love that it is patented:

Tried Out And Proven Successful!!!
This website was written - the English portion - and designed by Moshe Simon (845) 537-5102.
ImportantNotice:Please bear in mind that although this ring has indeed proven successful in at least 90% of the cases, no responsibility- and, of course, no liability -could be claimed in the event it does not live up to expectations. As we all Jews know, a person is judged in heavens and, based upon the outcome of the holy judgments, is rewarded and/or punished. A segulah – however powerful – might at some point in time need to be overruled for reasons totally beyond us, human beings. In other words, G-d created the whole universe and every single thing existing in it, including segulos. The power of a segulah is solely dependent on G-d’s will and it could well be reversed by G-d at any time without any notice whatsoever. Besides, all instructions are to be followed precisely; otherwise, the possibility that the segluah would not work is to be expected. When in doubt, it is advisable to contact Mr. Abraham Leib Shwartz at (845) 537-0041.Additionally, it should come to your attention that Mr. Ahraham Leib Schwartz was granted the patent to manufacture this segulah ring; no one else in the world is allowed to manufacture it at this point in time. Copying it would be against secular, as well as, religious Jewish law, and legal and / or rabbinical action will be taken in the event someone is caught committing such a transgression. Nor could any help from the segulah be expected when doing something of that nature against it.Also importantly, despite being mentioned after everything else, the ring cannot be lent to anyone else other than a very immediately close relative – wife, husband, and children. It is certainly to be kept in mind that no help could be expected from a ring that has been borrowed from a non-immediately close relative – cousin, uncle, and aunt – or from a friend.
