At Mack & Myyles, we use high-quality materials like gold-filled and gold-plated stainless steel for long-lasting jewelry. Gold-plated stainless steel is waterproof, tarnish-resistant, hypoallergenic, and biocompatible, making it the best choice for demi-fine jewelry. Gold-filled pieces offer the look and durability of solid gold at a fraction of the price, with a thick, bonded gold layer that resists tarnishing and wear. If your jewelry tarnishes within 365 days, we’ll replace it.
