This product includes a limited warranty card from the Gemological Research Association (GRA) and does not come with a certificate of authenticity due to the smaller size of the single moissanite (less than 0.3 carats). Made with 925 sterling silver, 18K rose gold plating, zircon, and lab-grown ruby with a weight of 0.14 carats. To maintain its quality, avoid wearing during exercise as sweat can cause silver chloride and copper sulfide to react and cause deterioration over time. Imported with chain length of 7.9 in and weight of 5.3 oz (150 g).
