The band Fun appeared on Saturday Night Live on Nov 3rd, 2012, performing their songs, Some Nights and Carry On. Fun's lead singer, Nate Ruess, was using a stylish gold-plated wireless microphone that was different form the Shure SM58 mics the rest of the band were using.
It turns out that Nate's mic was also a Shure - it was a Shure UR24D/SM58 microphone.
I'm not certain where you can get a gold-plated one like Nate's, but I'm guessing that if you can afford the Shure UR24D at about $2,300 ($4,659 for a pair), it would be nothing to pay extra for a gold-plated one.
If you are in the market for a high-end wireless hand-held microphone, you can get a pair of Shure UR24Ds like Nate's by clicking here, though you'll have to settle for the standard black color, unless you have a friend at Shure who can get it plated in gold for you;).
And if you don't quite have that in your budget, you can be like the rest of the band and pick up a Shure SM58 for a small fraction of the price of Nate's gold one (literally!) for about $98 by clicking here.
