This is a beautiful and elegant vintage brooch, measuring 1.5", from the 1940's-1950's. This has long navette sapphire blue rhinestones with a cluster of rhinestones between each stone with a larger 5mm round stone and then four other round clear stones that are approximately 2.5mm to 3mm. One of the larger stone is slightly grayed and in brighter light it is less noticeable - the rest area clear and equal in color. It is silver tone metal. It is not signed by the maker.
