Samsung's upcoming foldable phone, the Galaxy Z Flip, is basically still in rumor stage, but that didn't stop Russian jeweler Caviar announcing several pricy, fancified versions.

In contrast to some of Caviar's earlier work, which featured a garish Putin-themed iPhone, the Galaxy Z Flip remakes are actually quite cool.

The most interesting among them is the Caviar Samsung Z Flip Joker & Harley Quinn (yes, that's the official name), which features said characters on top and bottom of the phone's back, reminiscent of a playing card.

Of course, it wouldn't be Caviar without the golden details and the $5,210 price tag, but this thing would fit perfectly in the hands of James Bond's next villain. The phone is available for pre-order, but the delivery date is unknown.

Other customized versions include the Caviar Samsung Z Flip Gold, which features fewer characters from comics and more gold.

There's also the Caviar Samsung Z Flip Carbon Titanium, which, at $5,690, isn't much cheaper than the golden version.

There's not much more I can tell you about these phones, because we don't have the official specs of the Galaxy Z Flip yet. We should, however, find out more on Feb. 11 at Samsung's Unpacked event in New York City.
