Make a statement of minimalism with these dainty gold hoop earrings. Lightweight and versatile, perfect to wear alone for a smart-chic look or stacked with other hoops for a rock-glam vibe. 18k gold over 925 Sterling Silver. 18k gold plating is a wonderful option to get beautiful gold pieces at an affordable price. I only use top rated jewelry manufacturers that have been in business for years and have the repeat customers to prove it. Gold Karat plating can last for years when properly plated.
