You don’t have to be great at chemistry to understand why these isotope geometric brass earrings are the height of fashion…you just have to put them on! The unique pattern is beyond eye-catching and it provides a look that can work well with casual and formal styles. Despite the detailed pattern, these earrings come in at a surprisingly lightweight 16 grams. And with a 16-gauge size, they are guaranteed to fit most piercings including those that have been stretched beyond 16G.
