Gemstone rings or gem (also called a fine jewel, a gem or precious or semi-precious stone) is a piece of mineral crystal that is cut and polished form, is used to make jewelry or other jewelry. However, some rocks or organic materials that are not minerals (such as amber or jet), are also used for jewelry, and are therefore often regarded stones as well. Most stones difficult, but some soft minerals are used in jewelry due to their gloss, or other physical properties that the aesthetic value. Rarity is another characteristic that gives the value of the gemstone engagement rings. In addition to jewelry, from the earliest antiquity engraved gems and hard stone carvings such as cups were major luxury art forms. The jewel maker is called lapidary or gem cutter; worker diamond diamond. Ornaments from Carl Faberge as an important part of this tradition. The traditional classification in the West, which dates back to the ancient Greeks, begins with the distinction between precious and semi-precious; Similar differences are made in other cultures. The modern use of the precious stones diamond, ruby, sapphire and emerald, and all other gemstone engagement rings being semi-precious. This distinction reflects the rarity of individual stones in ancient times, as well as their quality: all are translucent with fine color in their purest forms, except for a colorless diamond, and very hard, with hardness from 8 to 10 on the Mohs scale. Other stones are grouped by color, translucency and hardness. Traditionally, the distinction does not necessarily reflect contemporary values, for example, while grenades are relatively inexpensive, can be green favorite garnet called to be a lot more valuable than medium quality emerald. Another unscientific term for semi-precious stones, which are used in art history and archaeology hard stone. Use of the term “precious” and “semi-precious” in a commercial context, it is likely misleading, that deceptively implies certain stones are really more valuable than others, which is not true. In modern times gemstone rings are identified by gemologists, who describe gems and their characteristics using technical terminology specific to the field of gemology. The first characteristic a gemologist uses to identify a gemstone ring is its chemical composition. For example, diamonds are made of carbon and beads of alumina (Al2O3). Next, many gems are crystals which are classified by their crystal system such as cubic or trigonal or mono clinic. Another term used is habit, the form the gem is usually found in. For example, diamonds having a cubic crystal system, are often found as octahedrons. Gemstone rings are classified into different groups, species and varieties. For example, the ruby red variety of the species corundum, while any other color of corundum is considered sapphire. Other examples include Emerald, aquamarine, red beryl, goshenite and Morganite, which are all varieties of the mineral species beryl. Gems are characterized in terms of refractive index, dispersion, specific gravity, hardness, cleavage, fracture, and sheen. They may have luminescence and specific absorption spectrum. Material or error in stone may be present as inclusions. Gemstone rings may also be classified in terms of their “water.” It is recognized classification luster GEM and / or transparency and / or “glory”. Very transparent gems are considered to be “first water”, while the “third water” gems as “other” or those less transparency. ValueEditThere is no universally accepted grading system for gemstone engagement rings. Diamonds are classified using the system by the Gemological Institute of America developed in early 1950. Historically, they were all gemstone rings assessed by the naked eye. GIA system included a significant innovation the introduction of 10x magnification as the standard for grading clarity. Other gemstone engagement rings are still assessed by the naked eye (assuming 20/20 vision). Mnemonic device, the “four Cs”, was introduced to the consumer understand the factors used to grade a diamond. The change may be in this category it is useful in understanding the assessment of all gemstone rings. Four criteria to bear a different weight depending on whether the use of colored gemstone rings or colorless diamonds. In diamonds, cut is the primary determinant of value followed by clarity and color. Diamonds are designed to sparkle, to break down light into its component rainbow colors (dispersion) chop up into bright little pieces (scintillation) and deliver it to the eye (brilliance). In its rough crystalline form, a diamond will do none of these things; This requires proper fashioning and this is called “cut”. In gemstone rings that have color, including colored diamonds, the purity and beauty of that color that is the primary determinant of the quality. The physical properties that allow colored stone valuable are color, clarity to a lesser extent (emeralds will always have a number of inclusions), cut, unusual optical phenomena within the stone such as color areas (uneven distribution of coloring within GEM) and ASTERIA (star effects). The Greeks, for example, highly appreciated Astoria gemstone rings, which were seen as powerful love charms and Helen of Troy was known to have worn star-corundum. In addition to the diamond, the ruby, sapphire, emerald, pearl (not, strictly speaking, a gemstone ring) and opal were also considered to be valuable. Until the discoveries of bulk amethyst in Brazil in the 19th century, is considered amethyst gemstone rings as well, it began in ancient Greece. Even in the last century certain stones such as aquamarine, peridot and cat's eyes (cymophane) they were popular and so was regarded as valuable. Today, such a distinction is no longer by gemstone engagement rings trade. Many of the gemstone rings used in even the most expensive jewelry, depending on brand designer fashion trends, market supply, treatments etc. Nevertheless, diamonds, rubies, sapphires and emeralds still a reputation that exceeds those of other gemstone rings. Rare or unusual gemstone rings, generally meant to include those gemstone rings which occur so infrequently gem quality that they are scarcely known except to connoisseurs, include andalusite, axinite, casiterite clinohumite and red beryl. Prices gem can vary greatly, or can be quite stable (such as those of diamonds). In general, prices of larger carat stones, which are higher than those of smaller stones, but popularity of certain sizes of stone can affect prices. Typically, prices can range from US 1 / carat for a normal amethyst US 20.000 to 50.000 for the collector three carat pigeon-blood almost “perfect” Ruby. GradingEditThere are a number of laboratories which grade and provide reports on gemstone rings. Gemological Institute of America (GIA), the main provider of education services and diamond grading reports. International Gemological Institute (IGI), independent laboratory for grading and evaluation of diamonds, jewelry and colored stones. The American Gem Trade Laboratory, which is part of the American Gem Trade Association trade organization of jewelers and dealers of colored stones. American Gemological Laboratories (AGL), owned by Christopher P. Smith. European Gemological Laboratory (EGL), founded in 1974 by Guy Marge in Belgium. Asian Institute of Gemological Sciences (AIGS), the oldest gemological institute in South East Asia, involved in gemological education and gem testing. Swiss Gemological Institute (chief), Henry Hanni founded, with an emphasis on color gemstone rings and identification of natural pearls.GUBELIN Gem Lab, the traditional Swiss lab Eduard GUBELIN justified. Each laboratory has its own methodology for evaluating gemstone rings. The stone can be called “pink” by one lab while another lab calls it “padparadscha”. One lab can conclude a stone is untreated, while another lab concluded that the heat-treated. To minimize these differences, seven of the most respected laboratories AgTa-liquefaction (New York) CISG (Milano), GAAJ-ZENHOKYO (Tokyo), Gia (Carlsbad), GIT (Bangkok), GUBELIN (Luzern) and chief (Basel) who founded Manual adjustment of the Board Laboratory (LMHC), standardization of reports of the text, the promotion of certain analytic methods and interpretation of results. Country of origin is sometimes difficult to determine due to the constant discovery of new sources of location. Determination of the “country of origin” is so much more difficult than determining other aspects of a gem (such as cut, clarity, etc.). Gem dealers are aware of the differences between gem laboratories and will use the derogations to obtain the best possible confirmation. Stones are used as the beads in a crystal form or otherwise, in which they are located. Most are cut and polished for use as jewelry. The picture on the right is from the rural commercial operation of cutting in Thailand. This small factory cuts thousands of carats of sapphire annually. The two main classifications are stones cut as smooth, dome-shaped stones called cabochons and stones which are cut with a faceting machine by polishing small flat windows called aspects at regular intervals at exact angles. Stones that are opaque or semi-opaque as opal, turquoise, variscite, etc. are often cut as cabochons. These gems are designed to show color or surface properties of rock such as opal and star sapphires. Grinding wheels and polishing agents are used to grind, shape and polish the smooth dome shape of the stones. Gems which are transparent are usually faceted method which shows the optical properties inside the stone to its best advantage to the maximum reflection of light which is perceived by the viewer as sparkle. There are many commonly used forms a layer of stones. On the sides should be reduced at appropriate angles, which varies depending on the optical properties of the gem. If the angle is too steep or too shallow, the light passes through and is not reflected back toward the viewer. Faceting machine is used to hold the stone on a flat lap for cutting and polishing of flat aspects. Rarely, some cutters use special curved laps to reduce and polish curved aspects. ColorEditThe color of the material due to the nature of the light itself. Daylight, often called white light, is actually a full color spectrum together. Until light strikes the material, most of the light is absorbed, while a small amount of a certain frequency or wavelength shows. Part of the reflected reaches the eye as perceived color. Rubin appears red because it absorbs all the other colors of white light (green and blue), while reflecting the red. The same material can exhibit different colors. For example, ruby and sapphire have the same chemical composition (both corundum), but have different colors. Even the same gemstone engagement rings can occur in many colors: sapphires show different shades of blue and pink and “fancy sapphires” exhibit a whole range of other colors from yellow to orange-pink, the latter called “padparadscha sapphire”. That difference in color, based on the atomic structure of the stone. While different stones formally the same chemical composition, they are not exactly the same. Now and then the atom is replaced with a completely different atom (and this can be more than just one of a million atoms). These so called impurities are sufficient to absorb certain colors and leave the other colors unaffected. For example, the readings which is colorless in the pure mineral form, becomes emerald with chromium impurities. If you add manganese instead of chromium, beryl becomes pink Morgan ite. With iron, it becomes aquamarine. Some gemstone rings treatments take advantage of the fact that these impurities can be “manipulated”, thereby changing the color of a gem. TreatmentEdit gemstone rings are often treated to improve the color or clarity of the stone. Depending on the type and extent of treatment, which may affect the value of Kama. Some procedures are often used because the resulting pearl is stable, while others do not take the most commonly because the gem color is unstable and may revert to the original tone. HeatEditHeat can improve gemstone engagement rings color or clarity. The process of heating is well known to gem miners and cutters for centuries, and in many types of stone heating is a common practice. Most vitrine is made by heating amethyst, and partial heating with a strong gradient results in Ametrin-stone partly amethyst and partly vitrine. Much aquamarine is heated to remove yellow tones and change the green color into the more desirable blue or enhance the existing blue color to blue cleaner. Nearly all tanzanite is heated at low temperatures to remove brown undertones and give a more desirable blue / purple. A large part of sapphire and ruby are treated with a variety of heat treatments to improve both the color and clarity. When jewelry containing diamonds is heated (for repairs) the diamond should be protected by borax acid; otherwise the diamond (which is pure carbon) burned on the surface, or even completely burned up. When the jewelry containing sapphires or rubies is heated, it should not be covered with a borax acid or any other material, since they can etch the surface; They would not need to be “protected” like a diamond. RadiationEditAlmost all blue topaz, both the lighter and darker blue shades such as “London” blue, has been irradiated to change the color from white to blue. Most greened quartz is also irradiated to achieve the yellow-green color. Emeralds containing natural fissures are sometimes filled with wax or oil to disguise them. This wax or oil is colored also emerald appears to be better, as well as clarity. Turquoise is usually treated in a similar manner. Filling has been in use with different gemstone rings such as diamonds, emeralds and sapphires. In 2006, the glass-filled rubies received the public. Rubies over 10 carats (2 g) with large fractures are filled with a lead glas, thereby greatly improving the appearance (large beads, in particular). Such treatments are fairly easy to detect. Synthetic and artificial gemstone is important to distinguish between synthetic gemstone rings and imitation or simulated gems. Synthetic stones are physically, optically and chemically identical to natural stone, but they are created under controlled conditions in the laboratory. Imitation or simulated stones are only to imitation, and can be glass, plastics, resins, or other compounds. Examples of simulated or imitation stones include cubic zirconia composed of zirconium oxide and simulated moisanite, both of which are diamond stimulants. Imitation copy the look and color of real stone, but they have neither their chemical nor physical characteristics. Moisanite actually has a higher refractive index than diamond and when presented next to another of the same size and cut diamond will have more “fire” than diamond. However, Synthetic, “culture” or lab created stones are not imitative. Na example, they were diamonds, rubies, sapphires and emeralds manufactured in laboratories that have the same chemical and physical properties of the natural variety. Synthetic corundum, including ruby and sapphire, are very common and they cost only a fraction of the natural stones. Smaller synthetic diamonds were produced in large quantities as industrial abrasives, although they are more gem-quality synthetic diamonds become available in different carats. Or gemstone rings is natural stone or laboratory created (synthetic), physical characteristics are identical.-Lab Created stones tend to have more vivid to them, because the impurities are present in the laboratory and do not alter the clarity or color of the stone, unless intentionally added for specific purposes.
