Jewelry gift, a pendant necklace from Devalier. Both the top and the chain sparkle brilliantly. It's been kept in the dresser, and it doesn't seem like I'll be wearing it anytime soon, so I'm hoping someone else can use it. Product Description: The large crystal is super cubic zirconia, boasting a sparkle that rivals diamonds. The chain is a luxurious Italian chain. The Italian chain has an easy-to-care-for platinum rhodium coating. Platinum rhodium coating RC processing is a popular coating method used in accessories to prevent discoloration and to reduce the likelihood of allergic reactions caused by the metal before coating dissolving. Rhodium is a very expensive precious metal and is one of the least likely to cause allergies. After use, gently wipe off any sebum or sweat with a dry cloth. The beautiful shine will last.
