Blue Rhinestone 'Triad' Brooch, Aurora Borealis - Mid Century -

A Blue Rhinestone 'Triad' Brooch with Aurora Borealis elements, likely from the mid-century, would be a vintage piece known for its sparkling and iridescent design. Here's what it would typically look like:

1. Shape & Structure: The "Triad" design often features a central cluster of three main elements or stones arranged in a triangular or trio formation. It could have either a geometric or floral inspiration, common in mid-century brooches.

2. Stones & Rhinestones: The blue rhinestones would be the focal points, usually made of glass or crystal. Rhinestones from this period were often faceted to catch the light, offering a lot of sparkle.

3. Aurora Borealis Finish: This would refer to a special iridescent coating on the stones that was introduced in the 1950s by Swarovski. The Aurora Borealis effect reflects a range of colors, mainly pinks, purples, and blues, giving the brooch an ethereal, rainbow-like sheen when it catches the light.
