See if you bought diamonds or pure gold.

If it is pure gold, the quality and purity are the same, and almost every family has styles, mainly depending on the price.

I think the winning numbers are very good. Those without diamonds were traded at the price of platinum per gram that day, while many styles of Chow Tai Fook were at the same price, regardless of weight. For example, the Platinum Association series endorsed by Zhang Ziyi, the same style, bought at the winning number is several hundred yuan cheaper than that bought at Chow Tai Fook, and the product quality is the same, but Chow Tai Fook's advertising fee is too high, and it is equally shared on each piece of jewelry.

If you really want big names, it's better to choose Tiffany or Cartier. These are the real big names, and they have more handed down value.
