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.
