The world's biggest diamond found in South Africa's North-West Province

THE world's biggest diamond - has been found in a mine in South Africa's North-West Province.
A South African radio station broke the news, reporting the stone found was twice the weight of the previous record-holder, the Cullinan Diamond.

The Cullinan weighed about 3,106 carats when found in present-day Gauteng province in January 1905.

The Cullinan was cut into several smaller stones, which now adorn the British crown jewels.
The stone was to be transported to Johannesburg under tight security, according to SAfm.
No further details were immediately available and a photograph of the giant rock has yet to be released.

Diamond mining in South Africa is dominated by the De Beers Group.

Inside Apple’s ultra-thin Air

MacWorld 2008 has been pretty much on expected lines. No real surprises this year from Steve Jobs, except for the world's thinnest notebook, measuring an incredible 0.16-0.76 inches. It weighs about 3 pounds (1.36 kg).

Air is powered by 1.6GHz or 1.8GHz Intel Core 2 Duo processor, with 4 MB on-chip shared L2 cache running at full processor speed and uses an 800MHz frontside bus.

Air comes with 2 GB RAM and 80GB hard drive.
