Blue Goldstone set

This Blue Goldstone set has tons of sparkle! Don’t let the name fool you, it is more of a deep purple which is the expected color. The necklace has an adjustable toggle clasp, 19 1/2 inches at its shortest to 20 1/2 inches at its longest. The bracelet also has an adjustable toggle clasp, 7 inches up to 8 inches. The pendant and earrings both have a 1 1/4 inch dangle. I’m not positive if this is silver plate or not.
