For most of our products we use pure 925 Silver which has purity stamp. For some products we use our specially formulated alloy which consists of silver, brass and other recyclable materials depending upon the product. We have mentioned all the details of materials used on the product page itself. All our products are nickel free and coated with 18k Vermeil , which is our special process for Gold Plating in 18k White/Yellow/Rose Gold (this coating is 50% thicker than traditional gold-plated pieces, keeping it beautiful for years to come).
