Swarovski Zirconia Platinum Plates Cross Pendant

Received as a gift. Never worn! Pendant: Platinum plated over sterling silver (925), polished finish and spring ring clasp. Dimensions, approximately 2.7cm x 1.7cm Chain: The 18” chain and clasp is sterling silver. I thought these were real earth mined or lab grown diamonds! I was shocked to find out they were zirconia. Absolutely beautifully well made zirconia! Purchased at a boutique. This is all the info I have on this piece 😊 I will send in a nice small gift box made for jewelry. 👌🏻
