Blue Aurora Borealis Round Brooch | and similar items

?Condition: Very good, no damaged stones, no metal wear or oxidation, under 50x magnification there are a few pinpoints of age on the backing of the Swarovski stones but I don't find it noticeable, external light is going to change how this looks. Bright natural light will look bluer indoor light it will look milkier. ?Size: 2 inches diameter ?Colors: milky opalescent blue, pale spring green, gold ?Marks: Unsigned, I'm confident this is a Sherman brooch, the prongs were filed after the stones were set which is one of the hallmarks of a Sherman piece ?Era: 1950s ?Materials: Swarovski milky blue aurora borealis pale green rhinestones, gold tone plated setting ?Style/Features: Step into the glamourous swirl of 1950s Hollywood with this stunning vintage wreath brooch that's equal parts ethereal and bold.

Sherman Co, renowned for their use of Swarovski rhinestones and flawless plating that stands the test of time. The gold tone plating and setting are in exceptional condition. Even under magnification there's no oxidation or metal wear, it's bright and shiny. A tight circular wreath of rounded navette rhinestones in translucent teal-blue-green, kissed with the original aurora borealis coating for that signature opalescent milkiness rainbow fire. Tilt in the light and watch the yellow-gold undertones pop alongside subtle greens, orange and pinks. It's not your standard clear blue sparkle, this mimics opals or moonstones.
