Vintage Juliana D & E Brooch. Light Blues. Lavender. shops 1950s Early 1960s. Vintage Costume Jewelry.

This is a lovely, magical piece, playing with the light to present subtle changes from light blue to lavender. Stippled or textured prong set stones along with faceted in a domed or cushion style. I think this one to also be a book piece, but can't be certain. I no longer have most of my reference books to cross check.
