This very pretty pair of vintage 1970’s clip-on costume earrings are set with simulated stones: iridescent pink Opals and Diamonds. These dainty cluster design earrings measure 10 mm diameter and 5 mm depth. Their reverse are embossed with a patent number. Although these earrings are not hallmarked, there are no signs of a base metal and I believe they are of solid silver. The condition is good; the wonderfully realistic foiled “Opals” are still brilliant and the “Diamonds” exhibit a lovely glittering effect. The only signs of age is one clip is very slightly looser than the other. I have road tester this earring and it still holds securely.
