For each of the earrings, I've set a vintage 1940s enameled metal cabochon in a serrated bezel on a sterling silver post. The cabochons are a silver tone metal with two crossed arrows on a turquoise enameled background. They measure about 5/16" by 7/16" and I've oxidized the settings, giving them a dark shine.
Due to the nature of the cabochons, I recommend taking the earrings out to shower, swim, or sleep.
The earrings will arrive all boxed up and ready for gift giving (or gift keeping). The last photo shows my packaging; those earrings not included of course.
