Hoops are Gold filled. 22 Gauge. 12mm in diameter. Please contact me with any special requests I chose these hoops specifically because they are easy to mold to fit your nose shape and size, they do not tarnish or lose shine, and they are light weight and comfortable for your piercing. I can create a custom nose ring for you if you have a special crystal or stone in mind. I have always enjoyed wearing a nose ring. I liked seeing different studs, shapes and sizes but I was never completely satisfied with my purchases. So I decided to create a nose ring that would not only look unique and beautiful, but also have natural healing elements to it. For example, Lapis opens the third eye and balances the throat chakra. Tigers Eye is my favorite crystal. Emotionally it alleviates depression and lifts mood. It heals issues of self worth and blocked creativity. So I went to my favorite bead store and hand selected each crystal. They are all natural stones. I can make special orders if you have a particular crystal you prefer.
