These are very unique earrings. The aquamarine in the middle actually spins inside the cage of the earrings. So when they dangle, they spin up and down. Other than being very cool, they are gorgeous to look at. These are brand new, sterling silver, stamped s925. From the very top to the very bottom, it is about 2.5 cm long, the widest part is about 1 cm. Gemstone is 5 mm. Comes in a beautiful box, perfect for a gift. Don't be afraid to make me an offer. Thank you so much for looking.
