The beauty of Serendipity is no accident. Each Australian blue opal is handpicked for its vibrancy and set in 14k gold. Note: All rings require an additional 3-4 weeks delivery time. Length: N/A Stone: Blue Opal Stone Size: 5/16 Metal: 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.
