Our factory since in 1995. The basic business is produce of stone jewellery. We are developing art style named fluid plastic and abstract forms. Our produce has great demand in all areas of Russia an other countries cause we have best quality and low cost.
Selenite is a crystallized form of gypsum. Chemically, it is a hydrous calcium sulfate. Gypsum is a common mineral that takes on a great variety of crystal forms and shapes. On the Salt Plains, the crystals are formed just below the salt encrusted surface. They are seldom found deeper than 2 feet below the surface. Crystals take on the characteristics of theirenvironment; the finer the soil, the more clear the crystals. Iron oxide in the soil gives the crystals their chocolate brown color. Because these crystals form in wet soil, sand and clay particles are included within the crystal. These particles often form an "hourglass" shape, found only in this area. Other foreign objects in the soil, such as sticks, rocks, bones, and even cockleburs, are sometimes included as the crystal forms. Single crystals, penetration twins, and clusters are the typical crystal shapes most frequently encountered on the refuge. Exceptional individual crystals measuring up to 7 inches long have been found, along with complex combinations weighing as much as 38 pounds. In certain places on the Salt Plains, gypsum and saline solutions in the soil are sufficiently concentrated to promote crystal growth. When temperature and brine conditions are ideal, the crystals may form very rapidly. When heavy rains or floods bring great quantities of freshwater to the plains, some of the selenite crystals may go back into solution until conditions are right for recrystallization.
