The centerpiece of these gorgeous agate earrings is a really beautifully carved banded agate. The unusual shape is rounded in the middle with tapered ends. At the top and bottom are smaller banded agates, 7mm. The design of these earrings is very architectural and really beautiful. The old style, locking lever backs test as 18K gold. The earrings measure 1-3/4" from the top of the gold ball to the bottom of the earring. They are 13mm wide in the middle. Each earring weighs 4.2 grams. The earrings are in very good antique condition. The hardware/wire holding the agates may have been replaced but the lever backs are original. Banded agate jewelry is always classic and never goes out of style!
