Thin Understanding Of Ruby (map)
Ruby What is Ruby? Ruby is the color the United States, transparent gem corundum. Ruby's English name is Ruby, from the Latin "Ruber", meaning red.
Ruby crystal clear beauty of color, by the ancient people to cast a mysterious supernatural color is regarded as auspicious objects. Back in ancient Egypt, ancient Greece and Rome, has been used to decorate mosques, churches and monasteries, and as a ritual tribute. It has also helped with the Diamond , Pearl Together to become King of the British Empire, the Russian tsar crown and the dress on the indispensable accessories. Since the last century since the stones into the civil, rubies are among the world's top five zhen Chen stone columns, is that people cherished gem varieties. World Gemological defined for the July birthday ruby stone. Ruby origin
little world, mainly in Myanmar, Sri Lanka, Thailand, Australia, China, etc. But in terms of quality gems to Myanmar, Sri Lanka, the best quality.
The shape of Ruby Ruby, including the most common form, such as emerald-shaped, pear, princess-shaped, oval and teardrop-shaped, etc., and diamonds are generally not the same round, the ruby is rarely round, heart-shaped nor more common.
Ruby Carat Weight With the same diamond, ruby, carat weight can also be used (or card) basis.
1 carat = 200 milligrams = 0.2 grams. One carat is divided into 100 copies, each called a point. 0.75 kt, also known as 75 points, 0.02 carat 2 points.
Conditions in other similar cases, as the ruby weight increases, its value is growing exponentially.
Ruby color Appreciation of the main concept of the ruby color, ruby red color to be pure, generally the concentration of the deep red color for the best price but will reduce the color too, such as Myanmar's "pigeon blood red" is the ruby in Need. Another point is the appreciation Ruby flaws. Ruby will crack, with no cracks and flaws in the ruby is extremely rare, which is "10 Red 9 crack." But the gem of the cracks, inclusions and other defects will not be too obvious, can not affect the overall appearance. Weight and cut gem is the key to affecting the grade.
Ruby Clarity Ruby the most common defects are small needle-like impurities, known as "filaments." Because each rubies are formed in their own unique environment, each containing stones are given the exact color of trace minerals and a unique combination of identification tags or impurities. Although Ruby is higher than the level of purity more than emerald, but the internal flawless ruby is very rare and expensive.
In light color and medium ruby color is generally more obvious impurities. As with the impurities generally ruby, so to choose deep ruby color, such impurities can be effectively hidden.
Ruby cut Different with diamond, ruby does not achieve the maximum bright and geometric designs by the cutting, such as diamonds, the "ideal" cut like.
The cutting gemstones in check to see whether the cut will be revealed in the beautiful gems. For example, darker color of the ruby, the best cut should be lighter than the average in order to allow more light through the gem, while the lighter color of gems, deep benefit cuts reflect the color.
The same as diamonds, colored gemstones of high quality there is also a tangent plane, crown, edge, Ministry, and the bottom of the dome. Dark ruby center area or bleached zone is too deep or shallow cut results. The well-cut ruby is symmetric, and uniform across the surface reflected light. Polishing should be smooth, no cracks or scratches. In addition, the cutting will not be a good show of ruby corundum crystals often appear in the ribbon: In this ribbon cutting is usually that those who want to retain as much as possible to cut weight, not the most beautiful stones.
Ruby economic evaluation based on Nature of Ruby, to varying degrees, there are certain shortcomings. The primary factor is the economic evaluation of color, followed by weight, transparency and clarity.
Ruby color value terms, to pigeon blood red the best, followed by red and pink roses. In general, Burma ruby red and bright, brightness large, the value of Thai-made than the high value of deep red rubies.
Nature of ruby particles smaller output, the value of precious stones according to the weight of the square of the upward growth, but if the weight of more than 5 kt gem above, we must separate bargaining under the gem quality.
Visual identification of Ruby Myanmar Mogok ruby. Stones often isolated pigeon blood red, rose red, pink. Color bright but uneven, often seen flat ribbon. Multicolor and clear, with the naked eye observation of gems from different directions, we can see two different colors. Double-crystal polymer film development, can see straight double-crystal shutter array pattern. Management often split along the three crystal faces split double poly film. Stones in different degree with the following inclusions: silk-like rutile inclusions; general fibrous rutile inclusions parallel to the six-cylinder ruby crystal distribution, forms three angle of 60 degrees and 120 degrees of the surface network, when the parallel This group of network packets of the cutting face, and refined into a cambered stones, when the light shines on the arc, there will be six shooting stars, or star ruby. If the fiber package takes the shape of irregular intensive accumulation, it presents a translucent milky white flocculent plaque. Diffuse-like fluid inclusions: the stones were scattered, the distribution of gas which occupies an area smaller, about 30%. If the fluid inclusions together was like fingerprint distribution, it is called the fingerprint-like fluid inclusions. Short columnar, granular network state inclusions: often with ruby spinel, calcite, sphene, hematite mineral inclusion. These small minerals due to melting and smooth edges. Sri Lankan rubies. Burmese ruby gem features and similar, but lighter in color, brightness greater. Ruby inclusions in Sri Lanka, in addition to a similar characteristics with the Burmese ruby outside, still contain two unique mineral inclusions: apatite inclusions, apatite hexagonal columnar, rounded edges and corners, there was a single crystal or groups ; silk-like rutile inclusions, compared with Burma ruby in the silk-like rutile inclusions slender.
Thailand bamboo spinning ruby tip. Stones were red with brown or rose red. Double-crystal polymer film development, flat ribbon and growth patterns. Inclusions less, but no rutile silk inclusions installed. Common fingerprint-like inclusions.

Why do minerals included in crystals appear in different colors than their natural state?
It fascinates me that individual minerals can manifest in so many different colors, but I have no idea what makes this happen.
For example, hematite, composed mostly of iron, naturally has a dark gray color much like the natural color of iron, but when hematite is found included in a crystal like quartz, it appears as deep red or even bright red. Furthermore, it can even appear a vivid orange color, such as the case of Tangerine Quartz, in which hematite dust is bonded to the surface of clear quartz due to extreme heat and pressure.
I've also read that aquamarines have their blue-green color due to minute traces of Iron.
Similarly, crystals with lithium inclusions, like lithium quartz and lepidolite, show a violet or lavender color, while lithium is in fact a silvery white metal.
Could someone explain how this works?
The color of an molecule is due to light coming in and exciting electrons to a higher state and then being released as the electrons fall back to their ground state. In their elemental state the electrons are at a certain ground state. When the element forms a molecule it accepts more electrons, thus raising the level of the ground state. This changes the energy released when the electrons fall into their ground state. The color of light is dependent on the energy of the light. So when the energy changes, so does the color.
