Sterling Silver Popcorn Chain 16." Made in Italy. Length: 16" Thickness: 2mm Hallmark: 925 25.4mm = 1" In order to preserve the original vintage/antique integrity of my items, I do not polish them. Most items can be polished by a professional jeweler in order to achieve a brilliant shine, but many customers prefer the original luster of an unpolished piece. My cleaning process is simply warm water and baking soda. Feel free to ask any questions. I encourage questions about my items, so I can provide the best customer service possible.
