Austrian luxury designer and jeweler Peter Aloisson has something more to add to his kitty – ladies and gentlemen, presenting to you the Aloisson designed iPhone – the world’s most expensive iPhone. The phone derives its name from the Princess cut used on 138 of the 318 diamonds on its surface. The rest of the 180 diamonds on the phone are brilliant cut and it has 17.75 carats of diamonds set in 18k white gold around its rim. All diamonds used are of the best quality.
