Vintage faux opal floral embossed brooch pendant beautiful colors

This is a magnificent unsigned pendant brooch combination, it’s in a floral design with tiny blossoms on the edge with a center cluster of stones, beautiful pinks, lavender and blues in a glowy combo. Pin back and pendant are excellent . Measures approximately 1.5” in diameter. No marked but looks like Originals by Robert with the filagree back, if not this designer it would be another in the 40’s to 50’s era. Please see all photos for full description.
