For people that have a lot of money to invest cellphone acessories, Miami-based company Miansai has produced a solid gold iPhone case. The case, which will run about $10,000, is a slip-on and is about 14 carats.

"We’ve seen some pretty high-priced iPhone covers before, but this one ranks among the most appealing," iDownloadBlog.com said of the expensive case. "No gaudy diamonds or jewelry bolted on – just classy, smooth, solid gold."

The case works for both iPhone 4 and iPhone 4S, and each is numbered and engraved for the buyer's pleasure.

Miansai said each case is made to order and is available in yellow or rose gold with a matte or polished finish. The case will ship within two weeks of ordering.

For those who love cellphone accessories that cost more than some cars do, Stuart Hughes is selling a diamond encrusted iPhone 4 for $20,000. Only 50 of these phones were made and they come unlocked for "worldwide use," according to Mashable. The device features 11.43 carats of hand-set, micro-pave diamonds.
