Jade is slightly thick, with acceptable water head, white background, high green degree and thin 1/5 cotton.
Chow Tai Fook has a certificate and the price is high. It can't be fake.
This jade clasp is expensive in dark green 1/5, and the others have no outstanding advantages.
7 100 price, personal opinion: outrageous.
"Gold is valuable, jade is priceless" is just a trick played by merchants, and every commodity has its market price.
I like the beauty of jade, not its name and inflated price.
The soul is priceless, not necessarily thousands of dollars. It's even more depressing if others don't know it's expensive.
Suggestion: Leave if you can, and choose another one.
You don't have to be a brand-name store, but online shopping is not recommended. Online shopping is even more difficult. You can buy it in a trusted shopping mall. Note: Many shopping malls in Jade are below 30% discount, which is the standard retail price. Usually, they are 50% or 60% off the standard price.
In fact, it doesn't have to be jade or expensive. Hetian jade, gold, etc. Can be used, mainly the mind.
