Jade A or A goods B goods B goods B goods B goods are two different concepts.

I'll help you check the certificate information of Chinese quality inspection technology.

Certificate No.20905000642 Sample submission No.

Inspection conclusion The total mass of Jade (A) bracelet is 60.93.

Shape/Specification Bracelet-shaped color light green with green.

Refractive index 1.66 (spot measurement) density is 3.33g/cm3.

Special inspection of fiber interwoven structure by magnification inspection method

This appraisal conclusion is indeed A goods. I don't know if the institution you re-examined is the national inspection institution. If it is a formal national inspection organization, it can ask the seller for compensation and the joint responsibility of the quality and technology testing center in the inspection.

Because the certificates and appraisal conclusions issued by Chinese quality inspection technology are completely legally binding.

Compensation is necessary.

I hope the answer can help you.
