The new black card: Take that, AmEx!

Dripping in diamond jewelry has always been the traditional way for women to display their wealth and status. Now they are not limited by rings and necklaces to prove their worth. A new credit card in Dubai comes embedded with a sparkling solitaire diamond.

The credit card, issued by MasterCard and Dubai First Royale bank, is invitation-only and has no preset spending limit. It isn't for just any rich folk. Only the wealthy, socially reputable Middle Eastern elite stand a chance to receive the coveted invites. Making millions doesn't automatically put you in the club. You've gotta be in the in-crowd, too.

An article on Emirates Business gives the nitty-gritty. The Royale MasterCard is solid black with a golden border, with a crest containing the embedded diamond in the middle. Each exclusive card is carefully handcrafted, taking 36 separate processes, including diamond setting and metal casting, to make one card. Only nine can be produced in a day.

Perks of being a cardholder include preferred access to a ritzy hotel, chartered yacht deals both in Dubai and globally and a "personal relationship manager to meet all their financial and lifestyle needs," the article says. The manager can assist in everything from booking jets to obtaining invites to exclusive events.

The American Express Centurion (aka black card) used to be the credit card of the elite. It looks like a new cowboy is in town.
