This piece is crafted with premium 16K gold plating for our signature lustrous golden tone and radiant finish. Measurements: approximately .5" long Materials: premium 16K gold over bras What makes our material and process different is that we use advanced plating technology and a gold layer over 30 times thicker than the industry standard to form a strong molecular bond that resists tarnish and fading — outlasting traditional gold plating and maintaining its brilliant shine.Our 16K gold offers a slightly richer tone than 14K and a softer warmth than 18K, giving it a modern, luxurious finish that complements every skin tone and pairs effortlessly with other jewelry in your collection. Each piece is waterproof, hypoallergenic, nickel-free, and lead-free—made to stand up beautifully to everyday wear and keep its glow wear after wear.We use brass as our base metal because it offers exceptional durability while remaining lightweight.
