Cuff links and studs are standard components of both military and civilian formal attire.

This set includes a pair of cuff links and four shirt studs.
Like mother-of-pearl, black onyx is frequently used for jewelry and decorative purposes, and their unadorned elegance make this set of cuff links and studs both eye-catching and versatile. The United States Navy specifically authorizes the wear of black cuff links by enlisted personnel E-1 to E-6 (Recruit to Petty Officer First Class); they are basic components (i.e., required) of the male and female versions of the Dinner Dress Blue / White Jacket uniforms, and are optional items for the female Dinner Dress Blue uniform.
