Chow Tai Seng and Kimberley are both national chain brands. Bandung is mainly supported by the flagship store opposite the Hangzhou Department Store, which is only a local brand and a regional brand.

Chow Dasheng is more famous and has obtained Chinese Well-known Trademarks and Chinese Famous Brands. Kimberley focuses on second-tier cities in many places, but Kimberley mainly makes diamonds, and Zhou Dasheng does everything.

Actually, the products are pretty much the same. In China, these brands are all passable. For diamonds, in addition to international brands such as Cartier and Tiffany, it is better to look at the price/performance ratio.

The price/performance ratio is very simple, just look at the 4C standards of diamonds, weight, color, clarity and cut. People in the diamond circle give similar prices for diamonds of the same grade.

If you care about the brand, look at the local brand that is better and has a better reputation.

Hope this helps!
