925 sterling silver vintage diamond cut flying sparrow stud earrings inlaid with a round red opal cabochon. Red opal can appear to have orange, yellow, and green accents in different lights and angles. Each earring measures 1/2 inch wide by 1/2 inch tall. Diamond cuts give these earrings distinct features that radiate under different lights, angles, and shadows in the way a diamond would. Vault piece~
