Handmade copper, brass, sterling silver, gold-fill, or rose gold-fill ear cuffs. They can also double as faux nose rings. Rose gold-fill or gold fill will not tarnish or change color. Copper, brass, and sterling silver will get a natural patina over time that can be easily removed with jewelry cleaner or a polishing cloth. Because moisture speeds up the tarnishing of copper and brass I would not recommend them for the nose. The large is approximately 1/2” round. The small is 1/4”. The item pictured isn't the exact one that you will be receiving, but the design will be as similar as possible. Each piece is made by hand so there will be slight variations.
