These bronze ridged huggie hoop earrings are head turners. With its Mexican artisana vibe these hoops have all the drama without the weight. The ridged discs are hollow to reduce weight and cost. We love the balance of modern and organic that come together in this huggie hoop design. Jewelry lovers appreciate hoop earrings they can wear with anything. Perfect for birthdays, anniversaries, Mother's Day, Valentine's, and Christmas! The outer diameter is 19mm and the inner diameter is about 10mm. The earring closes with a secure hinged post closure. The posts are sterling silver. Our bronze is a high quality Italian alloy of copper and tin that contains an anti-tarnish compound which delays, but does not eliminate, eventual oxidation.
