No, it's not safe. According to the information of Zhang Wanfu Jewelry Store, the jade bracelet bought in Zhang Wanfu Jewelry Store cannot be exchanged. Zhang Wanfu Jewelry Store stipulates that jade articles cannot be replaced after leaving the factory. Jade has low hardness and is easy to crack, even if it is slightly collided, it is easy to break, which is very unsafe. Therefore, jewelry stores generally do not exchange goods. Only diamonds, rubies and sapphires can be exchanged in jewelry stores. Because of its high hardness, diamond is the hardest substance known in nature, followed by ruby and sapphire.
