Heard of Goldgenie before? If not, let me introduce you them. The company has been providing 24K gold plating to many a premium devices in the market. So you can basically refer to them as high class phone design enhancer.
The HTC One M9 is the latest addition to their tally of devices for which they offer gold plating. Do note that their gold plating comes with a lifetime paint guarantee.
Nevertheless one would obviously require to shell a premium for it as the gold plated HTC M9 comes at $2,580. You can pre-order the device via this link but do keep in mind that you would be required to pay at least $1,280. Only then would the company get the device gold plated for you and ship it to your door via courier services.
The company would pack the device along with its accessories in a Cherry Oak Wooden box though to add to the premium feel - after all you have to pay quite a high price for it.
Just in case you already own the HTC device, Goldgenie has you covered. There is a provision to courier the device to their UK headquarters and from there they would handle the rest for you. But now the onus of deciding to sell a fortune for a gold plated M9 lies on you. After all you are paying just over four times the price of the normal retail unit.
