I've worn these c.1960s cufflinks numerous times and love them. Yes, tortoise shell and 12k gold filled (not solid gold) but of fine quality. Measurements are noted on the photos.
Very good to excellent condition for age and type, these are c.1960s, so vintage rather than antique. The shell canted rectangles have high polished shine and a superb beveled edge and gold mounting pin. Beautiful cognac to chocolate mottled color. My favorites!
