Is it permissive for foreigners to bring diamonds into Vietnam?
Is it permissive for foreigners to bring diamonds into territory of Vietnam? What does the customs declaration dossier include? My husband and I travelled abroad. Then, he gave me a 3-carat diamond ring as a gift. Do I need to have customs declaration for this ring when I come back to Vietnam? Thank you!
