Almost impossible. The crack of jadeite is one of the natural defects, and it is the enemy that affects the quality. I didn't find it when I bought it or it was cleverly covered up, and then I returned it afterwards. No business will agree. On the one hand, jade is not fake, on the other hand, you can't prove that the crack is not caused by your safekeeping mistake. Be careful next time. Be careful when buying jewelry and jade in tourist destinations.
