Gold cases

A case that matches the gold that will offer drop protection you say? If the case offers any protection then it'll cover the gold. Just an FYI.

As for cases, Marware has cases for the 5S, so they say.

Avivo Rail. Matching buttons and accents. 12ft drop protection and ability to be used as a bumper (personally hit a concrete sidewalk from around 5ft on the corner and there was only a scratch on the case). I plan on getting another for my new baby

Poetic atmosphere is clear in the back.

Spigen makes some transparent cases.

Any bumper.

You can find lots of cases for iPhone 5S sold on Otterbox and sw-box, just google these online stores.
