One of the oldest forms of jewellery made and worn in India is the kundan jewellery. Kundan work is a method of gem setting, consisting of inserting gold foil between the stones and its mount. Kundan work is often combined with meenakari, so that a piece of jewllery has two equally beautiful surfaces, enamel at the back end and kundan set gems in the front. Meenakari involves the fusion of colored minerals, such as cobalt oxide for blue and copper oxede for green. This gives the effect of precious stone inlay work on the surface of the metal.
Jaipur is the main centre of kundan jewellery. The famous Johri bazaar is the nerve centre of this craft. Nathdwara is known for its silver kundan work. Bikaner is also known for its kundan work.
