Gresso launches OTT luxury Avantgarde mobile phones

Look out Vertu, Gresso has launched its "Avantgarde" collection of luxury mobile phones.

There are two models available - the Sol, which would set you back around £3,400 - and the Luna priced at about £4,700.

What makes these phones so expensive? Well, each one is handmade from gold and 200-year-old African Blackwood so no two phones are alike.
