No, the pearl necklace bought in the live broadcast room is not reliable, because the products sold in Tik Tok live broadcast room are unknown, there is no specific information about the pearl necklace, and there is no jewelry appraisal certificate attached. I don't know the origin and material, so I can't personally feel the authenticity of the pearl necklace. Therefore, the pearl necklace bought in the live studio of Tik Tok is not reliable.
