This was given to my grandmother a long time ago. My grandmother is still alive! It is not an inheritance!!! It was given to her as jade. She treasured it, saying it was a good one. It seems she couldn't use it because it was heavy. It's quite old. The largest piece is about 1.8 mm. The pieces range from about 1.3 to 1.8 mm. It weighs 140 grams and is about 50 cm long. There are no markings on the clasp. ❇️ Please refrain from price negotiations. ❇️ Returns are not accepted to prevent item substitution. ❇️ There is no certificate of authenticity. It was a gift, possibly jade purchased overseas. I am selling it as a natural stone. Please understand this is an accessory. 0710
