The earliest known pewter (a metal alloy, consisting primarily of tin) was made in China 2,000 years ago. But tin was used by the Egyptians as early as 3700 BC and is mentioned at least twice in the Bible. The Romans used pewter for seals of office and other small devices. It reached its peak in the 17th century with master pewters in Brussels, Nuremberg, Paris, Antwerp, London, Boston, and New York. ​ The pliability of Pewter makes it possible to create elegant and complex jewelry designs as seen in this Long Boho Zipper-loop Necklace in pewter. ​ Hypoallergenic and suitable for those with sensitive skin. Jewelry features a beautiful 925 silver plating that provides a lustrous, high-quality finish. Pieces are made with nickel-free and lead-free materials.
