Very desirable vintage shirt studs in 18k, yellow gold. The tops are covered in patterned white enamel and each stud is flush set with a single, old European cut diamond. The combined weight of the diamonds is approximately .50 of a carat. The average clarity of the diamonds is SI1/VS2 and the color range is G-H. The diameter of each stud is just over 3/8 of an inch. ***Note- all 3 studs have small chips in their enamel on the edges but this will not be obvious when worn.
