Diamond jewelers make jewelry in diamonds from engagement rings to wedding rings, tiaras, necklaces and bracelets among others. Diamond jewelers may work in diamond alone or else pair it with other stones like rubies, pearls and sapphires. The price of diamond jewelry is dependant on carat weight, diamond colour, cut, clarity and shape.
