It is a little large and heavy, (about the size of an elongated 50 cent piece and as heavy as two of them) but it seems to be truly stainless, as is the chain.  It does seem as if it would be better suited for a man, but the weight and size of it reminds me of its presence often through the day and that is an added benefit I didn't think I needed but have found quite appealing.  All in all, I think this is an excellent value for the money, and I would recommend it to someone looking for an inexpensive but good quality medallion.
