Material: K10 Stone: Cubic Zirconia Length: Approximately 1.5cm from the ear hole The K10 hallmark is present, though small and difficult to see. I don't intend to include the sales certificate as it has my name on it, but please let me know in the transaction comments if you need it. Used only once. The cubic zirconia sparkles much more in person than in the photos. #JewelryTsutsumi #Estelle #4°C #canal4°C #StarJewelry #TheKiss #Wisp #K18Earrings #K14Earrings
