Tiffany & Co, This Art Nouveau glorious peacock brooch with diamonds, sapphires, emeralds and black opals was inspired by a design from the Tiffany Archives. Tiffany craftsmen created it using plique á jour, an enameling technique that allows light to shine through the enamel creating a stained-glass window effect.

"There are as many worlds as there are kinds of days, and as an opal changes its colors and its fire to match the nature of a day, so do I." ~ John Steinbeck

More than just a shimmering stone, opal — which is rich in water — has now been found in Mars' Gale Crater by NASA's Curiosity Rover.

Martian water ice is abundant at the poles but not so much at the equator (where Gale Crater is located). NASA's Curiosity Mars rover, which is currently exploring the crater, had previously beamed back data from its DAN (Dynamic Albedo of Neutrons) (opens in new tab) spectrometer, which was then analyzed by a team of researchers. In both older and newer Curiosity images, they noticed fracture halos, rings of light-colored sediment, that stood out because of their color; further tests proved that the light rock was actually opal.

Because opal is predominately composed of water and silica, the presence of this mineral could mean that there was once enough water there to possibly make the depths of these cracks habitable. Furthermore, the opal currently on Mars may one day be able to be harvested for the water stored inside, offering a source of water for any crewed missions to the Red Planet.
