Vintage Alice Caviness Glass and Plastic Turquoise Earrings

A very pretty goldtone metal setting on oval button earring featuring a high oval turquoise blue plastic cabochon prong set and a frame of opaque glass turquoise faceted stones. The dimensions are 7/8" Long x 3/4" Wide and 1/2" High. These earrings are in excellent condition appear new and never worn. Attachment is by clip on findings. The style indicates the year of manufacture to be 1960's to 1980's. As it is unknown when Alice Caviness went out of business and she died in 1983, I'm leaning toward circa  1970.
