It depends on what kind of jewelry you want to buy. If it is gold, the three brands are similar. The only difference is that Liu Fu's gold can be exchanged, but Dafu and Shengsheng can't. Platinum is definitely from Liu Fu, because of these three brands, only Liu Fu's platinum is sold by the gram, while Dafu and Shengsheng are sold by the piece, that is, the price of a piece is generally 900 yuan and 700 ~ one gram. Today, the price of platinum in Liu Fu is only 466 yuan a gram, and the processing fee is only a little more than that in 500 yuan, which is obvious. For diamond jewelry, different people have different opinions, but one thing is certain, Liufu's diamonds are of higher quality. For example, you will understand. I saw a two-carat diamond ring in Chow Tai Fook at a price of 79,000. You can imagine the quality of diamonds, but Liufu will never have diamonds of such poor quality. The quality of diamonds in Zhou Shengsheng is also good, but it is slightly worse than Luk Fook and Chow Tai Fook, which Zhou Shengsheng has always insisted on. To sum up, these three brands are well-known brands in Hong Kong, and they are all good! However, Chow Tai Fook's frequent quality problems in recent years have also affected its brand reputation, and its ranking has a downward trend. Personally, I think the cost-effective ranking should be Lukfook, Chow Tai Fook and Zhou Shengsheng. I hope I can help you!
