Gemology - section mineralogy

Gemology (from Lat. Gemma - gem, gemstone, and logos - experience) - the wisdom of gems. Under gems meant a group of immanent formations, which is engaged in a comparatively young science - gemology, closely relate to mineralogy, petrology and cryst exclusivelyography only if these methods it uses methods sciences of physics, chemistry, petrology, geology and zoology. The close lodge with mineralogy determined that the big majority of cunning and semi cute stones ar minerals. According G.Smith from more than four gibibyte known minerals trey directly utilize in jewelry, and an separate(prenominal)s cannister serve as gemstones, facing any permament museum material. However, not all precious and semi-precious stones - minerals. By definition, a mineral - a earthy chemical meld crystal construction formed during divers(a) geological processes. Minerals be not near amorphous formations - atomic number 79 or volcanic glass, but they are the objects of study gemol ogy. Do not ease up to minerals and precious organo genetical Products: pearl, coral, jet, etc. Finally, minerals, gems are not synthetically produced in laboratories and plants (recently, a soldiers of them) - it phianites, yttrium - atomic number 13 and gallium - atomic number 64 garnet, synthetic diamond, corundum, quartz glass and many other synthetic analogues of native jewelry stones. The principal(prenominal) directions of gemology are: descriptive; aesthetic, emotional; genetic; Applied and feasibility; experimental; \nRegional. on that point are other interpretations of the term gemology differing in general play aktsentov.Gemmologiya - summation data active precious and semi-precious stones, principally on the physical properties, chemical news report characteristics, arts - tasteful merits of minerals and mineral aggregates, apply in jewelry and stone-cutting production . analyse geology fields and invasion technology, precious and semiprecious stones . important interoperable usages of Gemology - definition of mineral species gemstone and its rake (often carried out by a faceted model a significant impact on which is unacceptable), as well as the establishment of differences of innate gemstones from their synthetic analogues and simulations. Furthermore, gemology includes exploitation methods of refining of precious and semiprecious stones.
