it's no secret we love a good hoop. they're so simple that they go with all the outfits, but they make us feel a bit more put together and sophisticated. this pair is is 14k gold filled- meaning you never need to take them out! they will not wear when exposed to water or moisture and are tarnish resistant. they are a flat hoop with "clicker" closure for easy on and off, also great for travel. they are simple and minimalist but will still make a statement. 30mm. hypoallergenic.
