    I was wondering if the casing of the iPhone 5 can be scratched by a 14k gold ring? I currently do not have a case on my phone and whenever I pull it out of my pocket I her my ring tap the case and I'm worried it will scratch. Do you think is a risk or is the iPhone 5 scratch resistant enough?

    Well gold and aluminum (not anodized) have about the same hardness on the Mohs scale 2.5 to 3.

    If the anodized process was "good" then it would be harder then gold.

    14K gold is not pure gold so I think it's hardness would be higher than the aluminum of the iPhone. It might scratch it.

    The problem is not the aluminum, is whatever coating they used for the 5. Haven't read the scratch gate posts?

    I decided to just put my hard case back on it to be safe.

    That's probably the best thing you could have done, IMO. Almost anything is able to scratch the iPhone, let alone a 14 karat gold ring.
