The twin protrusions that protect a central moonstone, are sharp enough to gash anyone that comes too close (Ok, so I'm sadistic). It is a size 11-1/2 and weighs about 1/2 oz. Made of Sterling Silver, the ring is very solid and very heavy, While it is not the heaviest, it ain't no spring chicken either.

If you like this design, but you need a different size or a different stone, I would consider making one of these for you.

Price = $110 + shipping and handling
