There are many metals and materials used for developing jewelry. Gemstones, coins and other precious items are very often used for creating jewellery items, and they are typically set into precious metals. Nearly alloy of every metal has been used for developing jewellery items. In Roman times, bronze was the most used alloy for creating jewellery. Now in modern times jewellery is made usually from the following metals, i.e. gold, silver, palladium, titanium, white gold etc. Mostly gold jewelry used in America and Europe is made of an alloy of gold, karats is the unit for its purity, presented as a number followed by K.
