These crawler studs feature two skinny crossed bars which make for a delicate yet bold silhouette. Studs measure 16 mm x 16 mm. Our materials make for an amazing, high quality, seamless, jewelry piece with longevity. Our earrings are plated with 18k gold, 18k rose gold, or rhodium and finished with a protective coating. A little secret we'll keep between us: it looks way more than it costs.
