Swiss luxury designer and jeweler Knalihs Athem, who earlier gave us the Apple iPhone 3G festooned with 475 brilliant cut diamonds, is now back with yet another stunning creation – the Diamond Vertu Constellation Gold.

Each phone is done in 18K gold and covered with more than 1500 brilliant cut diamonds. The handset can be personalized with initials, lucky number, logo or anything else you have in mind.

The Diamond-encrusted Vertu Constellation Gold is available in many design versions such as the Core Range, Precious Range, Monogram Range and the Rococo Range.

Prices, including the Vertu handset, start at $25,000.
