Why is vertu mobile phone so expensive?

It is made of gold, inlaid with diamonds, and the screen is also made of precious stones. The whole mobile phone is made by hand, high-grade material, of course, it is also very expensive. Moreover, it was invested by Nokia, and the brand image raised the price. And it is a luxury route, expensive and reasonable. But Vertu's mobile phone has no function, and some are even worse than hundreds of smart phones, which is the style of the picture.

Please accept it, thank you!
