Mother's rhinestone set

This is my favorite broche and earring set, and I wear it every time I need to dress up and out of my jeans and t's.

It is made with pink iridescent rhinestones, on goldtone metal. No markings.
Broche and clip-on (ouchymamma!) earrings.
Mom always said it was one of her good fake sets. She got it in the 50s, I got it in the 80s..lol
The colors and shine are beautiful! And the geometrical design is so easy to combine!

I'm not going to list it as a mystery, because I know where and when, but if anybody recognizes the set, and can tell me who made it, please do so. No markings or stamps. The clasp on the broche is the older safety clasp that you turn to lock the pin in place.
