The most expensive phone: iPhone 4 Diamond Rose Edition

It is hard to imagine today's world without cell phones, iPhones and other equipment, the new models of which cannot be called cheap. However, these amounts may seem like pennies when compared to the cost of the most expensive cell phones in the world.
The Guinness Book of World Records includes the iPhone 4 Diamond Rose Edition, which was made by the famous craftsman, jeweler Stuart Hughes. This small cell phone costs as much as eight million dollars. This model was paid for by the famous tycoon Tony Sage, who, incidentally, asked to make two copies at once. The back panel of the luxury phone is made of pink gold. As a decoration, 500 diamonds were used, the total weight of which was no less than 100 carats. On the back of the phone, there is an image of the Apple logo, for which 53 diamonds were used. The navigation button was made of platinum and is studded with a 7.4 carat pink diamond. Naturally, such a luxury should be kept in a proper case, which was made of pink granite and trimmed with nubuck inside. The weight of the case is quite considerable - about seven kilograms.
So far, this particular phone is considered one of the most expensive. However, the famous British designer Stuart Hughes worked on more luxurious models, which have not yet managed to get into the Guinness Book of Records. Many magazines believe that the palm belongs to the iPhone 5 Black Diamond, or "Black Diamond", which cost the mysterious businessman from China (he preferred not to reveal his name) 15.3 million dollars. And he planned to use this phone every day. It took a lot of precious metals and diamonds to manufacture. The body of the "Black Diamond" was made of solid gold, it took about 135 grams, the screen was sapphire crystal, and instead of the "Home" button, there was a rare black diamond weighing as much as 26 carats. On the case of the most luxurious phone, you can discern 600 white diamonds, and 53 diamonds were spent on the logo. The jeweler worked by hand and it took him about 9 weeks to make this miracle. In terms of features, it is the same phone as the other iPhones 5.
