A luxury mobile phone handset from Motorola is now available with a platinum and diamond case.

The KRZR is made from platinum and embedded with 336 Swarovski diamonds.

The £600 handset is manufactured by Goldstriker International, a firm renowned for its luxury gold and diamond mobile phones and iPods.

Meanwhile, the luxury goods company has also launched the world's first iPhone platinum.

Only 250 copies of the product, which retails for approximately £1,115, will be made available.

The most expensive mobile phone in the world was manufactured by Peter Aloisson, the inventor of luxury mobile hones, for an unnamed Russian customer.

The £0.65 million product was made out of solid platinum with rose gold and ebony features.

Aloisson made the keyboard using 28 round-cut diamonds and the on-off button from a one-carat natural blue diamond.

Each side of the phone is made from 25 carat princess-cut blue diamonds.
