LOVE my crystal trinity studs! My ears are incredibly sensitive to metals, so I purchased the 14k studs which are a step up from my normal 10k. My piercings were already a bit inflamed from prior earrings, but have healed perfectly with the 14k studs! No irritation at all. I pair these studs with a huggie hoop & gold bar stud- simple, delicate & gorgeous! Perfect to wear 24/7.
