The White Opal stone is commonly associated with feelings of Calmness, Serinity, and Clarity. Prong set in 925 Sterling Silver, each earring features a 6mm round White Opal as the center piece for this beautiful stud set. This is usually the average size for studs with gems, and won’t overload your ear lobe or weigh it down. Each pair will also come with a set of butterfly backs to secure the earring in the lobe. Hypoallergenic, water and sweat resistant. There is no need to take our tuned earrings off throughout the day or night.
