A woman's copper bracelet. In this example, the two pieces are not pushed together. Both ends are decorated on the front. In other examples, only one end is decorated. Metal was scarce in Oroch society, and valuable metal objects were preserved by each family. They were seldom sold, or bartered. At most, they might be used for paying a bride price. The Oroch were familiar with the forging of iron, copper, brass and silver. In addition to harpoons and arrow heads, they also produced knives, chains and metal jewellery. The metal was obtained through barter with the Chinese and Japanese, and later with the Russians as well. Ornaments like the item displayed here, are sometimes still worn by old women. They ceased to be worn by younger Oroch and Nivkh during the second half of the twentieth century.
