Necklace length adjustable from 29cm to 46cm Screw-back earrings Uses AAA grade cubic zirconia stones, the same as those used by famous domestic manufacturers, so they are clear, colorless, transparent white, and sparkle beautifully just like diamonds. I'm not sure if it's conveyed in the photos, but it looked like a high-quality item that was worth much more than the price. For those who want to buy at a bargain! Only the earrings were used for a few hours on the day of the event.
