Origin And History Of Ruby

Ruby The Luminous Red Jewels (Know As King Of Gemstones)


















Ruby is known for depicting the red color feeling love, power and grandeur. Red is the color of ruby is also known as "King of Germstones" which translated from the Sanskrit "ratnaraj" (king of precious stones). Ruby comes from the Latin "rubrum" or "ruber" (referred to as ru-Bor) which means red. Ruby also called "carbunculus" (carbuncle). Ruby is a precious gem on par with emerald, sapphire, and diamond. Since thousands of years, of India known as Ruby Country.

Ruby has a composition of "corundum" or korundum (aluminum oxide with chromium, Al2O3: Cr) is formed from the process alumunium oxide with other minerals such as quartz rock. Korundum word is taken from Tamil word "kuruvinda". Chemically, ruby occur as a result of binding oxygen atoms arranged in hexagonal close ties with the atomic alumunium that meets 2 / 3 of the space oktahedral. As a result, a very hard rock with a value of 9 on Mohs scale of measurement. Transparent red color occurs because the bonds alumunim, oxygen and chromium in this gem. There is also a ruby, pink to red to orange (orange). However, classifying gems on this classify as a ruby red and pink. Apart from this color, the color of any mineral or not korundum color known as sapphire. Only in the 19th century, people began to realize ruby sapphire share with family. Prior to that, considered with ruby spinel (such as Balas Ruby, Ruby and Timur Ruby Black is actually a spinel).

Ruby evaluated with several features such as character shapes, sizes, cuts, colors and flashes. Value is usually determined by ruby color red merahnya where the most light and best known as the "Pigeon Blood Red" (Red Blood pigeons). After the color, another feature in determining the value of ruby is clear (clarity), where high value can be inflated. However, clear ruby is difficult to be found in nature except ruby has been treated. This is because the native ruby typically have inclusion known as Rutile (titanium oxide) which forms a needle in order such as ruby stone (known as "silk").

Ruby has the natural characteristics of its own. As described earlier, the existence of inclusion known as the "Silk" is a feature that allows to distinguish genuine ruby and synthetic ruby synthetic. However, on this most ruby in the market have been treated. This ruby stone in the treatment adopted for the highlight color, flashes or features on the transparent ruby stone to add value in the market. Treatment includes modification to increase ruby color, increase transparency feature with separate inclusion, and improve the impact of any cracks.

Synthetic ruby in many markets that have characteristics that attract at reasonable prices. The process of making synthetic ruby has long been the practice since 1837. At that time, Gaudin made the first synthetic ruby alumunium by heating in a high temperature and chromium used as a pigment. In 1847, Edelman has released a white sapphire by heating alumina in the acid borik. In 1877, the Frenic and Freil produce crystals from korundum miles that can be deducted. Several years later, Frimy and Auguste Verneuil synthetic ruby produced by heating BaF2 with Al2O3 with a little chromium at high temperatures. In 1903, Verneuil synthetic ruby announced today can be made with a large scale for commercial purposes by a process called flame fusion which today is named after him Verneuil process.

Synthetic ruby made easier by using the Verneuil process for a cheaper cost. This indirect process such as the Pulling process, flux process, and hydrothermal process somewhat less popular. Synthetic ruby is usually added to the "dopant" (a type of semiconductor material known as a doping agent such as antimony, boron or phosphorus) that give flashes and features on the transparent synthetic ruby.

Ruby also has been artificial in the market since long. Synthetic ruby in the history has long been made by humans since the 17th century. At that time, Roman Civilization has produced a product of artificial stone which is processed to form ruby. In addition, several types of precious stones are often confused and sold as a ruby. For example rubbelite tourmaline and spinel.

Ruby is very difficult quality to be obtained. Although many minerals produced from mining korundum precious stones, not all of the highest quality for the market. Some emit flashes ruby star known as the star-ruby. This phenomenon occurs because the order of Rutile needles that are parallel to the form of cut stones that reflect light star-shaped with 3, 5, 6, or 12 blade flashes of light. Indirectly, star ruby prices can surge up as a featured special.

Ruby the famous and largest in the world known as "Rajaratna Ruby", with the weight 2.475 carats (495 g). Rajaranta ruby has asterism (flashes like a star), also known as star ruby. In addition, "double-star ruby" the world's largest (with 12 blade flashes star) is Neelanjali Ruby, weighing 1.370 carats (274 g). Now both are in the ruby reserve G. Vidyaraj from Bangalore, India. So far, the record in 2006, the most expensive ruby in the world ever auctioned off at a price of U.S. $ 5,860,000 with a heavy cut 38.12 carat cabochon-shaped.

Ruby was mined in Myanmar (formerly Burma). Although India is very popular with the ruby, ruby production nearly 90% of the world is actually concentrated in Myanmar. Myanmar is famous for its ruby color and shadow merahnya which has a ton of interesting colors. In addition, the color ruby, known as the "dove-blood-reddish" (or pigeon blood red) is also a valuable ruby from Myanmar (also known as Burma color). In Myanmar, the quality ruby can be found in the mountains and valleys surrounded by mountains in the area 200 km north of Mogok Madalay. In addition, the ruby is also available in other countries such as Thailand, Pakistan, Vietnam, Tanzania, Kenya, Nepal, Laos and Afghanistan. Ruby from Africa also have good quality because the color of interest.











Ruby is the birthstone for July.

Introduction About Gemstone And Advantages

History About Art Of Gemstone (Precious Stones)



















Gems
Since ancient times, precious stones used as a valuable ornament. In fact, precious stones were also used as a symbol of wealth, power and majesty of the ancient civilization. Precious stones treated by the world community as valuable because it is the most hard rock this earth.

In the past, people never thought that the stone has flashes of light and beautiful. Light-precious stones can be divided and reflected to produce rainbow colors, which cause it sparkling. However flashes gems actually depends on how it is cut. Precious stones are often associated with things mystical. Traditional medical practitioners for example, save precious stones like orange, red, black and yellow for the purpose of trapping energy such as foreign. Based on scientific research physicist, has miles of atomic structure with a strong low-frequency, slowly and favored by negative elements. However precious stones of pink, purple, white, green and blue found to have a relatively strong atomic structure and have a high frequency sound and speed.

Significant difference between the original gem stone common beauty, durability, hardness, difficulty to get it, how precious stones and drift emit light, and other features that are not common in stone. Many precious stones are mineral crystals or stones in the earth's crust. Precious stones have a specific chemical composition and atomic structure which are clustered in certain forms. Chemical composition is thus formed color, physical, and features that distinguish between precious stones each other. Gemstone weight is measured in carat value where one carat is 0.2 grams (1 / 5 of 1 gram).

Deduction form and precious stones should be done by experts and for those skilled in the beautiful gems to show beauty and beauty. When making cuts, experts will be possible attempt to obtain maximum possible weight in carat gem that. Discounts on stone also take into account Hardness (force), dispersion (light fraction), birefringence (refraction of light), cleavage (the distance between two corners), flaw (the original features that are not perfect), and inclusion (in effect in miles) . In addition, the cut gemstones by type of consideration to whether the transparent, translucent (semi-transparent) or opaque (light can not penetrate). Cut in opaque ordinary stone cabochon. Special features on some stones such as asterism (star) and cathoyancy (cat's eye) require a cabochon cut round or oval shaped with smooth surfaces and done by experts. Deduction requires many brilliant facet (surface-insulated terms) is often used for precious stones that showed flashes and transparent to the maximum emission of light and color that attract. Discounts on stone also highlight the luster (dibiaskan and the amount of light transmitted). Most gems have a vitreous luster, also known as glass-like luster (flashes such as glass).

Precious stones need hard and resistant to chemical changes with the frequent application. Hardness (Hardness) and durability (durability) is key in determining the gems. Scale of 1 to 10 are used to determine the force gems known as the Mohs scale. Scale was created by Friedrich Mohs a mineralogy from Germany and used as standards in determining the force gems. In the scale of hardness, the diamond is a stone minerals (10) and Talc is a mineral that most soft (1). Precious stones used for the appropriate use of the often hard and should be in value within 6 to 10 on the Mohs scale.

Although violence is an important factor in the evaluation of precious stones, one thing that is important also toughness (strength) of the precious stones. Diamond has a force 10 on the Mohs scale of mineral terkeras in the world but not so strong because there is actually a weak carbon bonds and can be broken if an impact is strong. Similarly, sapphire and ruby (value of 9 on Mohs scale), topaz (8), emerald (7.5 to 8), and several other gems can be broken if an impact is strong. In addition, there are also gems that hard but can not withstand the exposure to chemical or ultrasonic waves or ultraviolet light such as kunzite, tanzanite, and hiddenite. Strength (toughness) to the special features on some gems. For example jadeite that has force only on the value scale of hardness 7 but has the structure consisting of fiber-fiber bonded strong among each other to make it a gem that is strong enough.

Precious stones such as sapphire and ruby (corrundum group) can emit light like a star on the stone. This is due to fiber (fiber) is available in these gems. Star light flashes with 6 blades (six-rays) have 3 sets of parallel fiber. Sometimes, cutting precious stones can be cut to 12 blades emit flashes of light.

Value determined from the gem type, color, clarity (clarity), size (in carat weight), difficulty to obtain, popularity, and beauty. Diamond assessed using 4C; clarity, carrats, color, cut. If all those features have on the diamond, at market value would rise up. Diamond also be less expensive because of popularity while Alexandrite and emerald become expensive because of difficulty acquired. In fact, there are also gems to be so expensive is because in the collection of classes and the famous rich spinel as the crown of Queen Elizabeth or the emerald and ruby in the crown of Emperor of India (both now in storage in museums).

Apart from precious stones, jewelry man also made of plastic, wood, glass and fiber. Through sophisticated technology, it resulted in a variety of beautiful gems processed through human hands. Whether natural or artificial, it is still attractive as an ornament. This is the greatness of God and natural wonders of His creation is still largely untouched by humans.
