These 1"" hoops are hand formed of brass wire and finished with Argentium Sterling Silver Ear Wires. These are the perfect statement earring. These measure about 1"" long. If you prefer a bigger style hoop, check out the 2"" Basic Hoops for more of a statement. The brass parts of the hoops are sealed with a finishing wax to protect the shine and coloring for a long-lasting, beautiful finish. All of hoops are hand cut, formed, hammered, etc. which means they will all vary slightly in shape. That's the beauty of handmade, and I like to keep that element notable in my work.
