"[5] Burney further wrote of Cervetto "He was an honest Hebrew, had the largest nose, and wore the finest diamond ring on the forefinger of his bow hand", but considered him an indifferent performer.

His will, in which he left his son the substantial fortune of £20,000, stipulated that he should be buried according to the rites of the Church of England.
