It looks like a wrist band? But it is not made from cotton. This one of a kind bracelet is made entirely with tiny Coralizine Quartz gemstones knit together by elastic string. The tiny gemstones are leftover from cutting the large stones for the other items. They would not scratch your wrist or your clothes because they are all sand smoothed and polished. It is certainly a very good environmental protection. You may wear it for all occasion except when playing tennis. A new and innovative use of gemstone.
