The fan motif as a stud earring: CZ stones arranged in a radiating, wedge-shaped pattern in 14K gold over sterling silver that opens from a narrow base to a wider arc. The fan form has strong Art Deco associations - it appeared extensively in 1920s jewelry as a geometric expression of the era's architectural and graphic design sensibilities. Here Rachel Zoe uses it at stud scale for an earring that carries design heritage without historical costume. Butterfly back closure. A stud with a specific aesthetic point of view that rewards the wearer who notices design references.
