Montana Silversmiths Makin' Memories Crystal Earrings are the perfect small stud earrings for every memory-making excursion. The first thing that catches your eye with these stud earrings is the center clear cubic zirconia crystal. Surrounding the center crystal is a square silver etched design that radiates outward, and four smaller clear cubic zirconia crystals to finish the earrings. The simple studs are secured by a hypoallergenic post-back wire.
