It is normal for Chow Tai Fook's gold necklaces to weigh differently. Generally, a gold necklace is about 20-50g, but it depends on what kind of gold it is. If it is Chow Tai Fook's thousand gold, it is mainly 20-30g. Of course, if you have money, you just need to let me know. Even if you want a 10kg gold necklace, they can make it for you, and it will be quick.
