Diamonds will be discounted.
In fact, the best way is to set up a VIP, such as: Friends of Zhou Shengsheng (Zhou Shengsheng VIP), buy 20,000 yuan, then you can get a 10% discount on diamonds, and some special gold wares are free of manual fees or 10% discount.
Now, the price of gold is very high. It's really luck that one price a day is not cheap.
Which store? I recommend Zhou Shengsheng. Personally feel good, both in style and service. All my jewels are from Zhou Shengsheng.
