Product notice - the ends of the bangles are unfinished hence the price.Humans have been wearing copper jewellery for thousands of years. Copper is a trace mineral, which is essential for human health. It has antimicrobial, antioxidant, anti-inflammatory and anti-carcinogenic properties. Unlike many other nutritional elements, your body cannot synthesize copper and thus you need to get it from dietary sources. Some best dietary sources of copper are seafood, whole grains, lentils, nuts, seeds, cereals, potatoes, peas, chocolate and dark green leafy vegetables.14 grams Supplied by CopperCalmer
