This is a Dokra Necklace. Dokra is non–ferrous metal casting using the lost-wax casting technique. This sort of metal casting has been used in India for over 4,000 years. This is an unique gift for someone or for personal use.

Maintenance 

carefully remove all the dust accumulated on the Dokra jewelry. After that, get any brass polish, apply it on a dry and soft cloth rubbing it gently onto the Dokra jewelry or  use any Toothpaste which works wonders in maintaining the sheen of Dokra jewelry. Take a small drop onto a soft cotton cloth, and gently rub the cloth in minor circular motions.
