It can be delivered by express. Last year, I asked my sister to help me choose a model for my mother in Hong Kong. Chow Tai Fook's gold ring was mailed by EMS. Jewelry express, EMS and SF Express are preferred. These two companies are more secure, and the price should be insured and more assured when mailing. Hehe, I also sent a diamond ring by EMS. Haha, I filled in "handicrafts" in the item name column, which is safe.
