This gorgeous ring is made of 925 sterling silver and moissanite. It has a carat weight of 0.33. Please note that it does not come with a certificate of authenticity or a limited warranty card from the Gemological Research Association (GRA), as it contains less than 0.3 carats of moissanite. To care for your ring, please avoid wearing it during exercise, as sweat can react with the jewelry to produce silver chloride and copper sulfide, which can cause the jewelry to deteriorate and corrode over time.
