Sir Nugent is characterized by his extravagant display of jewelry, which consists of numerous rings adorning his fingers and an assortment of fobs and seals attached to his waist. His opulent appearance is so striking that it could easily lead one to mistake him for a jeweller promoting his collection.
This vivid description highlights Sir Nugent's flamboyant personality and serves to emphasize his affinity for ostentation, setting a tone of excess and perhaps even a humorous critique of his character's vanity and social pretensions in Georgette Heyer's "Sylvester."
