2014 has been declared the International Year of Crystallography (IYCr2014) by the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the International Union of Crystallography (IUCr).
IYCr2014 commemorates the centennial of X-ray diffraction and celebrates the important role of crystallography in the modern world.

CRYSTALS THAT FASCINATES  SCIENCE-BEAUTY & NATURE

Cave of the Crystals or Giant Crystal Cave  is a cave connected to the Naica Mine 300 metres (980 ft) below the surface in NaicaChihuahuaMexico. The main chamber contains giant selenite crystals (gypsum, CaSO4·2 H2O), some of the largest natural crystals ever found.[The cave's largest crystal found to date is 12 m (39 ft) in length, 4 m (13 ft) in diameter and 55 tons in weight. The cave is extremely hot with air temperatures reaching up to 58 °C (136 °F)  with 90 to 99 percent humidity. The cave is relatively unexplored due to these factors. The Giant Crystal cave was discovered in 2000 by miners excavating a new tunnel for the Industrias Peñoles mining company located in Naica, Mexico, while drilling through the Naica fault, which they were concerned would flood the mine.The mining complex in Naica contains substantial deposits of silverzinc and lead.
