This bracelet design was handmade in Miao ethnical minorities from miao silver. Miao people are well- known for their handmade jewelry which are in exquisite workmanship. Miao silver is a kind of silver alloy made by traditional miao technology. It contains 40% - 60% percent sterling silver. It looks darker than sterling silver and it's normal that the item has little blackish and yellowish, but it has a special rugged style which sterling silver can never show. It turns brighter while you keep it on your body.
