NASA's Landsat 8 Imager captured the shot of the giant chunk of ice.The diamond-shaped chunk likely broke apart from nearby sea-ice.

NASA spotted something incredible last month while taking images high above the Caspian Sea. A diamond in the rough.

Well, not a real diamond, but a stunning diamond-shaped chunk of white ice.

(OLI), a high-tech camera attached to the agency's Landsat 8 satellite. The photo comes from the cold and shallow northern region of the 600-mile Caspian Sea that stretches from Kazakhstan to Iran. It is the world's largest inland body of water.

The 'island' of white ice in the shape of a diamond is likely a chunk that broke away from a large field of nearby sea ice. While it may appear that the diamond is moving through the sea leaving a dark path behind, this is not the case.

Instead, NASA says the wind is pushing thinner darkerpieces of ice called "nilas" around the diamond leaving a shadow of open water behind it.
