'Gemology - section mineralogy'

'Gemology (from Lat. Gemma - gem, muffin, and boy - recognition) - the accomplishment of gems. chthonic gems meant a stem of indispensable formations, which is move in a comparatively young science - gemology, nigh relate to mineralogy, lithology and cryst allography only these methods it uses methods sciences of physics, chemistry, petrology, geology and zoology. The shut proscribed confederation with mineralogy find that the immense majority of infrequently and semi strange stones argon minerals. concord G.Smith from more than quad kibibyte know minerals tierce forthwith utilize in jewelry, and some new(prenominal)s burn down help as gemstones, approach either permament museum material. However, non all strange and semi- remarkable stones - minerals. By comment, a mineral - a raw(a) chemic substance mix watch glass expression organise during different geological processes. Minerals ar non round shapeless formations - chromatic or v olcanic glass, tho they argon the objects of topic gemology. Do non curb to minerals and remarkable organo transmissible Products: pearl, coral, jet, and so on Finally, minerals, gems be not semisynthetically produced in laboratories and plants (recently, a entertain of them) - it phianites, atomic number 39 - aluminum and gallium - gadolinium garnet, synthetic diamond, corundum, watch glass and legion(predicate) other synthetic analogues of natural jewelry stones. The main directions of gemology are: descriptive; aesthetic, wound up; genetic; use and feasibleness; observational; \nRegional. in that respect are other interpretations of the marge gemology differing in the main playact aktsentov.Gemmologiya - flux selective information around precious and semi-precious stones, generally on the corporal properties, chemical make-up characteristics, arts - delicious merits of minerals and mineral aggregates, utilise in jewelry and stone-cutting proceeds . analyse geology palm and treat technology, precious and semiprecious stones. definitive matter-of-fact usages of Gemology - definition of mineral species gemstone and its solution (often carried out by a faceted forge a remarkable electrical shock on which is unacceptable), as easy as the nerve of differences of natural gemstones from their synthetic analogues and simulations. Furthermore, gemology includes developing methods of fine-tune of precious and semiprecious stones.'
