Afghan craft mens make all these necklaces one by one and by hands. All of the crafters are self employed and make these items by taking orders. The metals used in these kind of jewelries are called different names, some call it German Silver, some called it Gypsy and some call it Alpaca Silver. However, just like Tibetan Silver, they don't give body reactions or allergies. The metal don't change color either. These Jewelries have been in the market for centuries.
