In oxidized sterling silver, these moonstones radiate their own cool light. A link-style design makes these Legacy hoop earrings modern and memorable. Length: N/A Stone: Moonstone Stone Size: N/A Metal: Oxidized Silver / 14k Yellow Gold Due to the natural state of stones used by Nina Nguyen Designs, each piece will vary. Naturally occurring variations such as shape, color, shading, color concentration, thickness, texture, etc, are to be expected, are not flaws and not considered a manufacturer defect. Oxidized silver results from a chemical reaction. This darkened color will naturally change and polish with wear, adding depth and character to the piece and is not a manufacturer defect. Do not polish with silver polish, as this will remove the treatment.
