Nokia unveiled two new mobile phones this week, the 7500 and 7900 Prism branded handsets that feature a diamond-cut design, sharp angled lines, geometric patterns and graphic light-refracting colors.

The Nokia 7900 is the top-of-the-line Prism model, and includes an anodized aluminum back cover and an Organic LED display on the front, the company said in a statement on Tuesday. It will support 3G networks and include a 2-megapixel camera, as well as 1-gigabyte of memory.

Similarly styled, but with less features, the 7500 will run on GSM networks, popular in the United States.

Nokia says the phones target "style-conscious consumers.'

The two mobile models will be available in the third quarter of 2007 with an estimated retail price of 400 euros (US $550) for the Nokia 7900 Prism and 210 euros ($289) for the Nokia 7500 Prism, before taxes and subsidies.
