Final answer:
Meyer Wolfsheim's cufflinks made of human molars demonstrate his wealth and possibly symbolize his criminal connections, serving as a tool to impress and unsettle Nick in 'The Great Gatsby'.
Step-by-step explanation:
The character Meyer Wolfsheim in The Great Gatsby draws Nick's attention to his cuff buttons, which he points out are made from human molars, as a way to demonstrate his wealth and level of sophistication, albeit in a macabre and unsettling way.
These molars could symbolize Wolfsheim's ties to the criminal underworld, as someone who literally wears his disdain for social norms on his sleeve. The cufflinks serve as an ostentatious display designed to impress and perhaps unsettle Nick, showing that Wolfsheim is a person who is both affluent and not bound by traditional moral standards.
