Yes, all SMUK earrings, including the post part, are made entirely of 925 sterling silver. While some products on the market use posts made of brass with silver plating, SMUK is committed to using solid sterling silver throughout—even in areas that are not visible—crafted with care and integrity. For gold-plated items as well, we ensure that the entire piece, including the post, is fully coated. We prioritize not only appearance but also comfort and quality. Because the post comes into direct contact with the skin, we focus on creating designs that can be worn with confidence and peace of mind.
