The ring is fully made of 925 sterling silver, handcrafted in Poland. Nickel Silver (Alpaca) is great silver alternative, but make sure you’re not allergic to nickel or zinc, it has a darker color than 925 silver. The crafting time for this product is 2 to 4 weeks, as each piece is individually made to order. Crafting time for Nickel Silver (Alpaca) might be a little bit longer at up to 5 weeks. This duration can alternate depending on the demand of our customers.
