In fact, this is not made of steel of any sort. It is non-ferrous. Also, the bumps that stand in for beads are too tall, which makes the ring uncomfortable to wear for any length of time.

The purpose of a finger rosary is to have it with you always. I know that discomfort will keep me from wearing it, and I suspect that whatever the material is would not stand up to continuous wear.

On the plus side, it IS all pretty and shiny and would take up less room in one's pocket than an actual rosary, so if you're looking for something to carry rather than to wear, it might be worth a try.
