Emerald, this ancient gemstone variety, is luxurious, noble and glamorous. It is also known as the world's four famous gems with diamonds, rubies and sapphires, but not as famous as diamonds and red and blue gems, but it often does not care about the world's incomprehension and neglect. The so-called high place is not cold, emerald is the leader in expensive gems, and it can be called the artifact of the "Bao Fan" vision.
The best emerald resort:
Colombia
The distribution of emeralds is not unique and is found in many countries. The earliest discovered and mined emerald mine in the world is the Cleopatra deposit in Egypt. But the real large-scale mining was in 1537 in Colombia, South America, with the highest output and the best quality, accounting for 80% of the world's total production, about 2 million carats of emerald raw materials. In addition, Zambia in Africa, Zimbabwe; Australia in Australia; Brazil and other countries and regions in South America have produced, but the quality can not be compared with Colombian emerald.
The most critical price factors:
Rare production
Although emeralds are produced in many parts of the world, the quality of emeralds is still far below the production of diamonds of the same quality. Almost one out of every 1 million beryl minerals is emerald. Emeralds are brittle and easy to crack during the mining process. The emeralds, which are difficult to mine and have scarce production, are well-deserved rare stones.
The most attractive charm:
That touch of green
The color of emerald is very attractive. Some people describe it with spinach green, green onion, and green bud green, but they can't accurately express its color. It has a yellowish green color, and it seems to have a little blue. Even the spectrum seems to be missing the dot wavelength. Indeed, no natural color makes the eyes so comfortable. Whether it's cloudy or sunny, whether it's an artificial light source or a natural light source, it always glows softly and radiantly. This is the charm of the emerald green king of green gems.
The most important criteria for judging:
Color
The green color of emerald determines its value. Too light or too deep is not a good product. Medium green and beautiful luster are called the best. The chromaticity is thick and vivid, and the tone is medium to medium. Good transparency and even color distribution. Even a slight chromatic aberration will have a huge impact on prices. It is generally believed that the emeralds produced in Colombia's most famous Chival mining area and the Qiwa mining area will be slightly blue, which is considered to be the best quality emerald.
The most demanding elements:
100% pure
Although the more clear and precious, the emeralds are mostly transparent, but the impurities are therefore more easily seen by people. This visible flaw is a basic basis for confirming "natural" gemstones.
Natural colored gemstones will not be 100% pure. Impurities and cracks are the characteristics of all natural gemstones. There are sayings of “Ten Treasures and Nine Cracksâ€. Colored gemstones mainly rely on their own color to win. The purity requirements cannot be compared with diamonds. Judging the standard drawing equal sign.
The best cutting method:
Emerald cutting
The most common of the main cutting methods of emeralds is “emerald cuttingâ€.
Emerald cutting used to be mainly used in emeralds to reduce the enormous pressure created during cutting, thus protecting the gemstone from cuttings. This technology is now widely used in many types of gemstones. The number of facets of the "emerald cut" cut gemstone is about 50. The emerald cut is viewed from the top like a rectangle with a corner cut off. With a stepped facet, it can be a very beautiful gem; the brilliance of these steps will show the brilliance of these stepped corners on the gemstone pavilion.
