These earrings have Chinese writing on the back which says 100% silver. They were not made for export. I believe the jade is from old court jewellery and the earrings were made at a later date. The jade had a beautiful fire to it, very hard to capture on camera. The earrings are silver that has been gold gilt and the jade cabs are 5/8 inch by7 /16 inch. Condition is good with no chips or cracks to the jade. The earrings backs are screw type.
