Vintage 2 in. rhinestone brooch or pin. Pins on the diagonal for a diamond shape. No markings of any kind so other than being vintage, I cannot comment on the rhinestone material or the silver tone hardware content. Some of the rhinestones are more sparkly than others, for example the ones at the four corners are a little more dull than some of the surrounding ones. I don?t know why that is but it lends character. See photos. It?s not overly pronounced.
