Vietnamese company Karalux is now offerings a Black Gold plating service for the iPhone 6s, in addition to its original 24K gold-plating.
The colour is achieved by mixing gold with rhodium in a specific ratio. The company’s technical director said that rhodium itself is 6 times more expensive than gold.
The process of covering an iPhone 6s with Black Gold takes 8 hours and as you may have guessed, it’s not exactly cheap. A 64GB iPhone 6s dipped in the rhodium/gold pot will set you back about $3000 CAD.
