De Paiva established good relations with
East India Company (EIC) and those in power, which enabled him to buy several mines to source
Golconda diamonds. Through his efforts, Jews were permitted to live and trade
Golconda diamonds and corals within Fort St. George. De Paiva died in 1687 after a visit to his mines of Golconda diamonds and was buried in the
Jewish cemetery which he had established in Peddanaickenpet, which later became the north Mint Street, ==Philanthropy==
