A quatrefoil is a 4-lobed ornament that usually consists of 4 partial and intersecting circles. It was one of the symbols used extensively during the gothic era. The motif reoccurs periodically as a jewelry design theme. The jewelry firm Van Cleef & Arpels is noted for its use in their Alhambra line.
