Since each piece is handmade, there may be slight variations in design and/or color. We think this makes each piece special and unique! 18K gold-plated (hypoallergenic and nickel-free) 25mm hoops. Earrings are handmade with polymer clay – handle with care! While a little water will not hurt your earrings, take them off before swimming and showering, and store away from extreme temperatures, oils, and perfumes. To clean, use some gentle soap on a damp cloth and gently rub the area that needs cleaning. Do not bend your earrings! While polymer clay is generally flexible, bending your earrings may cause damage or breakage. Handmade in Virginia.
