The engineers took the phones apart, a process that takes 10 steps. The flagship duo is made out of 7000 series aluminum, 60% stronger and lighter than stainless steel. Those metal parts are than taken through a complicated process to first lay a base, then gold plate them and finally put on a protective layer on top. It's the same process that was used to gold-plate this Rolls-Royce.
The gold-plating process alone costs VND 8 million ($355), phone + gold plating is VND 25 million ($1110). If you're in Hanoi, you can visit the Karalux Store where the gilded phablets are available for viewing.
