Elegant, classic artisan sterling silver overlay size 8 ring features a naturally included oval white/rainbow moonstone. Unlike other types of moonstones, rainbow moonstone belongs to the feldspar group along with labradorite, and thus flashes color when in certain light. This stone shows subtle blue flash for a surprising effect. Stone size is 14x18mm. Please see last picture for sizing guidelines. Reasonable offers accepted and thanks for looking. ☺️ Bundle and save!
