An intriguing pair of 18K yellow gold cufflinks, the faces set with triangular cabochons of labradorite. In bright lighting conditions, the stones exhibit the unusual play of bluish-greenish color desired in labradorite. The color seems to emanate from within the stones and float on the surface over the gray and cream body color. Each of the cufflinks is stamped with French 18K marks and an unidentified goldsmith's mark (S.Cie. with an anvil).

An extremely rare pair of 18K yellow gold and citrine cufflinks by the mid-century Brazilian jewelry designers Roberto and Haroldo Burle Marx.
