In September 17th, I bought a ring at Zhou Dafu. The appraisal date on the certificate was May 6, 14th. Will this be refurbished? Is it appropriate to buy 1W?

For Zhou Dafu, it is not very high, and the brand is more expensive. As for the certificate only proves that the diamond ring was sent for inspection for 14 years, but it did not sell it for three years after returning, it does not indicate that it is refurbished.
