Late 20th-Century Hidalgo Plique A Jour Enamel and Diamond Dome Ring

This late 20th-century 18k gold ring features a striking design with brilliant-cut white diamonds. The diamonds, with a total carat weight of 0.5, are set in a pattern that highlights their H color grade and SI1 clarity. The ring showcases a vibrant orange plique-à-jour enamel inlay, creating a bold contrast with the diamonds. Crafted by Hidalgo in the United States, this piece could be sized to some degree, but the enamel would limit how much it could be sized.
