This is a lovely and elegant pair of antique Victorian earrings in 10K rose gold set with onyx. I believe these were intended as mourning jewelry. They are marked on the back Pat Sep 8 1883. They are unmarked as to gold content, but acid test to at least 10K. The stones have been tested with a gemstone tester. The original backs have been replaced with ear wires.
They measure about 5/8 inch by 1/2 inch and they are in very good condition.
