I bought a diamond ring in Tongling. I think a good brand is mainly from the aspects of quality, reputation and service. Tongling's main products are diamonds and jadeite. Diamond cutting is very good and should be considered second to none in the industry. Emerald is also very good. Their employees are very professional and will recommend products suitable for customers from their perspective. The after-sales service is also perfect, and the brand reputation is very good. So I think Tongling's brand is very good.
