Must-read for purchase: Natural A-grade jadeite beads are authentic, and we support re-inspection by any organization. We will compensate you ten times if the product is fake. We support complaints. Manual measurement and natural characteristics will inevitably have an error value of 0.5mm. If the product is not from the same batch, there will be a little color difference. Due to natural characteristics, each one is a unique natural material. A little white line is natural ice crack cotton wool, which is not a defect. I hope all buyers and friends will know and understand! Thank you for meeting!
