The English name for Ruby is Ruby, which is derived from Latin and means red. It belongs to the corundum mineral and the trigonal system. It is red to pink because of its chromium content. The higher the content, the brighter the color. Blood red ruby ​​is most cherished by people, commonly known as "pigeon blood red." Among the ruby ​​reds, the most valuable is the most intense color, known as the 'pigeon blood' gem, very expensive. This bright and intense color, which can be called the deep red color, reveals the true face of the ruby. Unfortunately, most rubies are light in color and have a powdery feel, so rubies with pigeon blood tones are more valuable. In addition, because the ruby ​​is filled with strong anger and rich colors, former people think it is the embodiment of a dead bird, and it has an ardent illusion. The origin of natural rubies is sparsely populated, the quality of ruby ​​is only produced in Myanmar, and the output is gradually decreasing. Now it can be said that almost the decline has been exhausted, and the big gemstones no longer appear. Ruby sometimes has three beams of six stars. These star-shaped rubies are cut into a curved dome of a smooth vault. Starlight is most visible when illuminated with a single source. This color effect is known as the starlight effect and is caused by light reflected from the fine rutile needle-like inclusions. The acicular rutile inside the ruby ​​is oriented parallel to the crystal surface. The value of star ruby ​​and star sapphire is affected by two factors: 1. the intensity of body color and the degree of fascination; 2. the intensity and sharpness of starlight. The six legs of the star line must be straight and equally eye-catching. Starlight ruby ​​is difficult to achieve both the ideal translucent or transparent color and the narrow and narrow starlight. Such gems are valuable and expensive. The world's largest star ruby ​​is the star ruby ​​of Rajara, India. The gemstone weighs 2,457 carats, has a six-shot star, and has a dome-shaped dome. In 1991, a red and sapphire continuum was found in Changle County, Shandong Province, China. It weighed 67.5 carats and was called “鸳鸯 鸳鸯 gemsâ€. It is a rare miracle in the world. In the international gem market, the bright red ruby ​​is called “male ruby†and the light red is called “female rubyâ€. The area around Mogok, northeast of Mandalay, Myanmar, is a major producer of quality rubies.
