The mineral's chemical formula is sodium lithium boron silicate hydroxide, — LiNaSiB3O7(OH). It was discovered in November 2006, in a mine at the Jadar Valley in Serbia.Jadarite's chemical formula is very close to the formula invented for the fictional chemical kryptonite in the 2006 film Superman Returns. This coincidence attracted mass-media attention, and Jadarite was covered by ABC, BBC, CNN, Washington Post, and Yahoo, among others. Google hits exponentially increased in one week time after such publications.The new mineral, unlike the fictional material in the movie, does not contain fluorine and is white rather than green (although, in the Superman comics, there is a variety of kryptonite colored white). However, in all other respects the chemistry matches that of the rock containing kryptonite in the movie. The jadarite fluoresces a pinkish-orange color when exposed to UV light.Jadarite<img src="http://newsimg.bbc.co.uk/media/images/42835000/jpg/_42835709_kryp_nhm_203b.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Category     - MineralChemical formula -     sodium lithium boron silicate hydroxide                                   LiNaSiB3O7(OH)Molecular Weight -     219.46 amuColor -     whiteCrystal habit -     cryptocrystal, massive, polycrystalCrystal system -     MonoclinicMohs Scale hardness -     hardLuster -     glassyUltraviolet fluorescence  -    blushStreak -     whiteSolubility -     acidsDiaphaneity  -    clear to opaque</blockquote>
