18K GOLD VERMEIL - Our gold vermeil jewelry is a heavy 18K gold plating over sterling silver. To ensure the plating lasts a long time, store your jewelry in an airtight container when not being worn. In addition, plated jewelry should not be worn in swimming pools or while bathing, putting on perfumes or hairspray. If you would like to clean your plated jewelry, please do not use harsh chemicals - even jewelry cleaners. Gently rub using mild soap and water for best results.
