Until recently, the vast majority of mobile phones had been priced between £100 and £300, with only Vertu, a division of Nokia, manufacturing uber-premium phones.
With prices starting at around £4,000 Vertu phones are only for the filthy rich, and the super famous.
However, Vertu's monopoly of the luxury phone market is coming to an end with the launch of several new luxury mobile makers, including Gresso, Mobiado and GoldVish.
Other mobile phone manufacturers are also partnering with luxury brands to produce a range of premium mobile phones, such as LG and Prada, D&G and Motorola, and now Tag Heuer and Modelabs.
Finally, there are the ridiculous, super-expensive one-offs, made purely for headline grabbing, such as Goldvish's "Le million", worth a cool $1,000,000, see below for details! 1.
Goldvish "Le million" = $1,000,000 (£540,540) A PR stunt it may be, and they surely can't be expecting to sell any, but the Goldvish "Le million" is officially the most expensive mobile phone in the world, according the Guinness Books of Records.
There's even been talk of a $1.
3million phone, but this has fewer diamonds than the Goldvish so I can't see where the extra expense comes from! The "Le million" is a one off, featuring a blinding 120 carats worth of VVS-1 grade diamonds, according to designer Emmanuel Gueit.
If $1 million is out of your price range.
the Geneva-based Goldvish also offer several other diamond-encrusted 18k gold models in your choice of rose, yellow, or white, starting at a much more reasonable $25,600 (£13,837).
Vertu Signature Cobra = $310,000 (£167,567) Vertu is now taking orders for the Signature Cobra, designed by French jeweler Boucheron, but you had better be quick as only 8 are being made! The Cobra will feature one pear-cut diamond, one round white diamond, two emerald eyes and 439 rubies.
Vertu will also be offering a "cheaper" version, ruby free, at $115,000 (£62,162).
Sony Ericsson Black Diamond = $300,000 (£162,162) Apparently the Black Diamond will be available in 2007, not from Sony Ericsson but by a company called VIPN.
Initially only 5 unique numered pieces will be available for the unbelievable price of, wait for it...
With regards to the specifications, don't expect anything remarkable for your money.
It will have Quad-band with Wi-Fi, an Intel 400Mhz processor running windows mobile 5, and a touch sensitive 2″ screen.
It will also include internal memory of 128mb and will come with a 2Gb SD card for external storage, plus a respectable 4 Megapixel camera.
The designer Jaren Goh has used some pretty impressive materials for the build, featuring titane with polycarbonate, mirror-finish cladding and diamonds.
Vertu Signature Diamond = $88,000 (£47,567) The Diamond is Vertu's premium range of high-end mobile phones.
As the name suggests the handsets in the Diamond range are diamond-encrusted handsets made from platinum.
Only 200 of the handsets are being produced, the most expensive believed to be worth an estimated £50,000.
Motorola V220 Special Edition = £28,000 ($51,800) Austrian designer Peter Aloisson, has taken a standard Motorola, studded it with 1,200 diamonds and added a keyboard inlaid with 18 carat gold.
The outcome is a £28,000 handset, suitable only for footballers and film stars!
