Gresso has announced the Black Diamonds and the Royal Black Diamonds models.The high-roller Gresso Avantgarde collection handsets are hand-crafted from the exotic African Black-wood. Gold elements cover the mobiles from head to toe.

The back panel is made out of stainless steel but is covered by scratch-resistant hand-polished titanium. Attention has been paid to every detail and all the materials used - sapphire crystal glass surrounds the QVGA TFT 65K color display while the titanium-covered keypad comes with laser-cut Roman numerals. Other notable features include the magnetic lock of the battery cover and the use of gold for the screws and some of the keys.Both mobiles have a  2 mega-pixel camera and run Windows Mobile 6 Standard OS.

The Gresso Avantgarde Royal Black Diamonds mobile has a full keypad made of gold - all 23 keys are encased with black diamonds. Since those diamonds are extremely rare only a limited series of 50 mobiles will be ever produced. The Gresso Avantgarde Royal Black Diamonds will be selling at EUR 30 000.

The Gresso Avantgarde Black Diamonds mobile will feature only four black diamonds. The rest of the keys are made out of gold only. The expected retail price of the Gresso Avantgarde Black Diamonds is EUR 9000.
