These hoop earrings are made of sterling silver 925 and coated with 18k gold. They are small, at 10mm, and the minimalist design that fits snugly against the ear is feminine. As they are hoop earrings, they are catch-free, so you don't have to worry about losing the catch. These are cute and sophisticated earrings that can be worn for a wide range of occasions, from casual to formal. They will be carefully packaged, but will generally be simply wrapped. Thank you for your understanding.
