**UPDATE** It seems as though TW3NTY is not the designer behind the above gold 9900. The rightful designer is Amosu Couture!
The above image is part of the listing on eBay. For $1500, you can get the gold bezel put on your phone.
An exert from their ad:
23RD (TW3NTY) has now released the latest BlackBerry 9900 with the bezel plated in 24ct. Gold. Be the first to get one of these luxury phones made by TW3NTY.
Another company called Goldgenie also does gold bezeling, and even a platinum bezel! The platinum version is the one you see below. Not sure of the pricing on that one because it was a custom service. Goldgenie mostly specializes in Apple products but can also do Blackberries.
