Ruby's origin less, mainly distributed in Myanmar, Thailand, Sri Lanka, Vietnam, India, Tanzania, and China.
Most of the world's ruby was found in alluvial deposits in small areas. The more valuable the ruby of their living environment more harsh. Similarly, the ruby is very difficult mining conditions, for example, in Burma ruby, usually stripped of thick cover to reach 15 feet with gravel stones. Then, can we truly be mine.
Gradually from the large gravel filter out fine as a beautiful gem like Ebb Tide. This carefully selected work, spent a lot of manpower, resources and time, when we finally got out one shining gem brilliant light, the eyes will emerge out of the river carrying the memory of the most beautiful music of the scene - rare gem thus more valuable.
Different origin, the conditions of exploitation are not the same ruby. Natural output of ruby are also different:
Myanmar
There are two main origin of Myanmar rubies, one of Myanmar Mogok; the other is Burma Bangladesh prime.
Myanmar Mogok is the world's most beautiful ruby origin, known to pigeon blood red, so that "Burma Ruby" became synonymous with commercial quality ruby. Myanmar Mogok ruby with bright red roses - the highest grade of red known as "pigeon blood red", that is pure red, and high saturation. Significant fluorescence under the effect of sunlight, its various facets showed a bright red, shiny. Often rich in small rutile needles fog to form stars. Uneven color distribution.
Meng Su is the ruby found in the 90's the new place of origin, in Mogok, about 200 km southeast. Meng Su ruby red to purple to brown, ruby crystal at the center of the core common with dark blue purple, after heat treatment, deep blue purple stain somewhat removed, and Chenganhongse to red, sometimes white floc formation, lead to reduced transparency. In addition, the Bangladesh prime ruby is also common in parallel with the growth of the bottom.
Thailand
Thailand is also a major producing countries and ruby trading center, it was reported that nearly 70% of the world, producing high-quality rubies from Thailand. Ruby origin accounted for him in southeastern Thailand, Buri. Thai Ruby Fe content was high, darker, less transparent, more Chenganhongse - brown. Non-daylight fluorescent effect, only in the light than bright direct facet, the other facet is black. Uniform color. Lack of rutile-like inclusions, so no star ruby variety.
Sri Lanka
Sri Lanka to transparent ruby, known for soft colors. And larger particles, the color changed greatly, from light red to red, pink, reddish brown or brown red to cherry red. Bright red high-end product is slightly pink and yellow, often called red cherry red or water. Also the ribbon development, rutile needle thin, long and uniform.
Tanzania
Tanzania Common ruby purple color, orange red, and pink and red is less, and Ruby with high Fe, Ti, and the relatively low Cr. Fracture healing of ruby without most of them filled with foreign particles, and to decrease the transparency of the ruby.
Vietnam
Vietnam in the late 80's found several rubies new place of origin, such as land security in northern Vietnam near the city of ruby deposits in the central province of Nghe Cai Cai Zhou village, city ruby deposits, and basalt in the southern region of the ruby deposits. Ruby Lu An output of which the largest, best quality, second to Caizhou ruby, ruby are both taken from the residual and slope sediments. Vietnamese ruby color from pink to red, and more with purple hue, rare pigeon blood red, the color of a stream striated banding phenomenon.
China
China Ruby mainly found in Yunnan, Anhui, Qinghai, where slightly better than the ruby. Of the ruby distribution produced in the western Yunnan area Ailaoshan metamorphic phlogopite marble, but mining is a secondary ore value, which mined rubies size 1-10mm, color was red and red roses, nuanced and uniform. But the split management and development, inclusion and high impurity content, most can only be used as arc precious stones, with gem quality faceted rare original stone.
