These delicately crafted links very clearly illustrate the skill of the craftsmen who were producing fine objects during the time of the Mughal Empire. Each has been expertly fashioned from a single piece of nephrite jade, which is a hard and durable material that requires patience and skill to work.

Tayler was educated in England at Charterhouse and also spent a term at Christ Church, Oxford. He entered service with the East India Company on 30th April 1829, arriving in India in October of the same year. He held various posts in Bengal and was appointed Commissioner of Patna in 1855. During his service, he was able to acquire many objects, including hardstones, relating to the customs and religions of India as well as objects from other parts of South Asia. He was criticised for his handling of the uprisings in Northern India and was moved to a lesser post before being suspended, ultimately resigning on 29th March 1859. He then practised as an advocate in the law courts of Bengal before returning to England in 1867. He wrote a book about his experiences, entitled Thirty-eight Years in India in which he states that "After my return to England, circumstances induced me, though with great reluctance, to part with the collection which is now in the South Kensington Museum".
