Is it cheap to buy gold jewelry in Hong Kong? Be in a hurry

Recently, my wife pestered me to buy Chow Tai Fook's apple soft bracelet. The current gold price in the mainland is 455. This soft bracelet is about 4500. I want to ask my friends, is the gold price of Chow Tai Fook in Hong Kong the same as that in the mainland? How much cheaper if you buy it in Hong Kong?
