The Spice Girls have used £1 million worth of jewels to decorate the cover of their greatest hits album. The band - Victoria Beckham, Mel B, Emma Bunton, Mel C and Geri Halliwell - will release the LP later this year to coincide with their world tour, which starts in December. A special one-off edition of the album will have the word 'SPICE' emblazoned across a white background with each letter decorated with a different gem, representing each of the girls. The S is made from amber and represents Victoria, the ruby pink P represents Emma, Mel C's I is made from diamond, Geri's C is made from sapphire stones while the E is made from emerald and represents Mel B. A source said: "The album cover is a nice touch. They wanted something simple and stylish and it's probably one of the most expensive album covers ever made."
