For your consideration are these long and interesting onyx sterling drop earrings. The tops are onyx and they carry sterling drops. The earrings have a nice modernistic look. The marks are very hard to read but one is sterling and I also see part of the 2 number 2 letter sterling designator that was used in Mexico after 1979.
They are a nice size measuring 2 and 1/4 inches in length. The tops measure 5/8 inches across.
They are in excellent condition. Cleaned by previous owner. Comfortable and secure on my ears.
