Brooch Vtg Large Bejeweled Shades of Blue Swirled Rhinestones Brooch

This is a gorgeous 50s unsigned vintage brooch. It features an elegant, stacked cascading swirling design arrangement of muli-faceted rhinestones that form a spray motif (to me it looks like a question mark). It has navettes in a deep sapphire blue and ocean blue, with icy blue chatons that separate the two navette tones creating dimension and added sparkle. It is in a rhodium plated silver tone setting, this plating was used to prevent tarnishing and increase durability. It's approximately 3 inches long at its longest point and approximately 2 inches wide at its widest point.
