All of our silver jewelry is solid sterling, with a stamp of authenticity. Pure silver is far too soft to used in functional objects. Sterling silver is 92.5% pure silver, and 7.5% other materials, usually copper. Copper gives it its strength, while at the same time preserving the ductility and beauty of the precious metal. Over the years, most countries in the world have developed their own systems of hallmarking silver. The purpose of hallmark is: To indicate the purity of the silver alloy used in the manufacture or hand-crafting of the piece. To identify the silversmith or company that made the piece. All of our sterling silver bears the "925" stamp/hallmark. European beads are fantastic keepsakes, and can last lifetimes, if cared for, cherished, and passed down.
