Emerald is known as the "king of green gems", and it is regarded as "four precious stones" by diamonds, rubies and sapphires by the international jewelry industry. Following Jade, it is leading the round of green jewelry collection in the Chinese jewelry market with strong momentum.
Because the value of emeralds is uneven, people often ask: What is the price of a carat emerald? The answer to this question is actually a very difficult question. It can be said that the price of a carat of natural emerald ranges from tens of dollars to tens of thousands of dollars. The influencing factors generally include color, weight, transparency, clarity, cut, place of origin, and whether it is soaked; because the bottom of the emerald is very shallow, the refraction The rate is low and there is less flare, so first look at color and transparency / clarity (crystal fineness), and whether it is foaming, weight, cut, place of origin, etc. In addition, faceted emeralds are more valuable than plain emeralds, and occasionally there are plain emeralds that can achieve investment-grade levels because of their high quality.
In short, the value of one carat of high quality emerald is higher than the same one carat of top color white diamond, and the price of one carat of low quality emerald is no different from ordinary crystal. The price of emeralds changes every period, and the overall trend is gradually increasing.
LAC International Jewelry, based on the background of international diplomatic resources, has the world's leading jewellery designer's superior resources and has an absolute purchasing power advantage in the global raw ore wholesale of rubies, sapphires and emeralds. As an influential importer and exporter of precious stones, whether in the emerald international auction market, wholesale or in the general retail market, the experience is very rich, invited to interpret the 2015 one-carat emerald market:
1. One carat of high-quality faceted emeralds (similar to the quality of the emeralds are generally accompanied by an international certificate), the color is rich, the naked eye is very flawless or naked, the crystal is delicate, if the origin is Colombia, Zambia and Brazil Etc., according to the quality of its quality, its price per carat is more than 1000-1500 US dollars; but if it is the Colombian Muzo, Chival and other famous mining areas such as Panjer in Afghanistan, the price is at least doubled; if it is the same quality and oil-free If the price is to be doubled, the higher the weight of the same quality, the price will rise in accordance with several times. Because of its beauty and scarcity, high-quality emeralds will have a large investment value-added space in the future with the popularity of Chinese and other consumers.
2, one carat with a medium quality, medium-sized, slightly sinuous, crystal-like emerald, according to its quality, its price per carat is between 300-1500 US dollars.
3, one carat of general quality, color gray light, enamel inclusions and crystal turbid quality of the emerald, according to its quality, its price per carat is between tens of dollars to 300 dollars, But even if it is cheaper, it is not recommended to buy, because there is no room for appreciation in the future.
This is because the output of emeralds is extremely rare, and only one of every 1 million beryl minerals is emerald; emeralds are brittle and easy to crack during mining, and the production is difficult to produce. Rare emeralds are well-deserved rare stones. In addition, factors such as political instability and capital operation have also been greatly affected.
In the famous emerald mines in Colombia, such as the MUZO mine, there are many well-guarded armed groups, which basically control the large emerald areas of Colombia. The armed forces are basically divided into two forces, one is the local underworld, and the other is the guerrillas. There are often armed conflicts between them. If foreigners want to go there to visit or mine, it is simply a matter of death, because there will be patrols with guns at any time. For those who are foreign, they don’t care about your motives, and you may be put to death at any time. .
In 2013, Lac Diamour, a subsidiary of Lac International Jewelry, officially entered China's well-known e-commerce platform. Its senior expert Jamespan interpreted the investment of one carat of emeralds:
1. About China's emerald consumption environment
China's emerald consumption environment is very chaotic, based on several factors:
The emerald collection investment in China's consumer environment has just started: China's real economic take-off time is also decades, and the professional atmosphere of collectible investment in precious jewellery has just begun.
The biggest marketing lie in the Chinese market: owning quality mining areas. There are many domestic sellers who claim to have mines in Colombia. Most of them do not have a small nameless pit, or they take an abandoned mine as a scorpion. Because in the local area, there are only gangs and guerrillas who really have high-quality mineral resources, and the sellers do not directly deal with the buyer. They have to sell the goods through the middle trading company. Of course, these middle trading companies are basically local. The rich class is all.
Non-professional companies disrupt the market shoddy: There are many domestic sellers who claim to be professional emeralds. Because they do not have professional skills and international level of appreciation, they sell large quantities of low-priced, low-quality, uncollected emeralds to disrupt the market. The truly high-quality, collectible emerald cannot be circulated to consumers because of its high value and high price.
Synthetic or colored oil emeralds disrupt the market: there is a kind of “cultivating emeraldsâ€, which is made by grinding and purifying the natural quality of beryl, and then cultivating it by high temperature and high pressure. Its characteristics are bright and dazzling, crystal clear and very attractive. These artificial gemstones sometimes appear in the jewelry store designated by the travel agency. Don't see the beautiful gemstones plus the ultra-low discounts of the merchants, thinking that they have won the grand prize. Because the quality of pure natural emerald is expensive and will never be discounted, although the artificially cultivated emerald is also made of natural beryl, the price will vary greatly. Another kind of oil that is green in color is not a natural emerald, but it will be treated.
2. How much do you want to collect emeralds?
Some people often ask, how much is it best to collect emeralds? The collection of emeralds first considers the quality of the emerald, then the weight. Generally, the crystal crystals of emeralds are not large. After cutting, the color purity is excellent, and it can be up to 1 carat or even more than 2 carats. It is rare. If the weight is above 5 carats, it is a rare treasure. More than 20 carats is an extremely rare rare treasure.
3. The best emerald resorts - Colombia, Afghanistan and Zambia
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. Today, the production of emeralds is more famous, the first in Colombia, the quality of the emerald produced by the famous Musuo and Chival mines is recognized as the best. However, the emeralds of Panjerhir in Afghanistan are bright and bright, and their production is scarce. In addition, the emeralds produced are hard to find and the prices are high. In addition, Zambia, Brazil, as well as Africa, Asia and many other also produce emeralds, but high-quality natural emeralds are rare and worth comparable to high-end diamonds.
4. Why do emeralds have more cracks and more impurities?
The standard for the purity of emeralds is that the colored gems are relatively loose. In fact, there must be some cracks and inclusions in the emeralds; the complexity of the types of cracks is even more complicated by the researchers. Emerald garden." The inclusions in this kind are innate, the most characteristic of which is the gas-liquid-solid three-phase inclusion, which is a triple structure of gas, liquid and solid in a package, which is also important for distinguishing Colombian emeralds. One of the features.
Emeralds are hard to find innocent; clear and unmistakable emeralds are extremely rare, and a cleaner emerald of more than 3 carats is quite rare and expensive.
The main component of emerald is strontium aluminosilicate, which contains trace element "chromium". Emerald is formed because a part of "aluminum" is replaced by "chromium". From a chemical point of view, "chrome" and "aluminum" cannot be combined together. Therefore, this displacement reaction needs to be carried out under extremely special and extremely complicated geological conditions. At the same time, in the process of the emerald, there are many other elements such as mica, pyrite, calcite and the like, so there are many impurities. In addition, because of its long-term growth cleavage, and its brittleness, it also cracks during mining, so the final quality of emeralds is small, which is why it is expensive.
5. The emerald-shaped cutting surface has the highest value:
The emerald has a high hardness, but the texture is brittle and easy to be crushed by gravity. In order to maximize the weight of the emerald and avoid the accidental fragmentation of the emerald during the wearing process, the cutter developed a creative idea for the gem. A special cut: emerald cut. This stepped cut cuts the four corners of the gemstone, and the outer contour is an octagonal rectangle or square, which can completely reflect the light entering the gemstone while preventing the corners from being mechanically stressed; More gems are often cut into semi-circular shapes (Cabochon) or popular beads in India; also Colombian emeralds, the price difference between the cut surface and the egg noodles, emerald cut than oval The positive circle is more valuable.
6, emerald inlay and maintenance
Although the hardness of emerald is high, it is brittle and easy to be brittle. It is prone to chipping during the inlay process. If you buy bare stone and then inlay, it is best to choose an experienced professional emerald custom company, or buy the mosaic directly. Finished finished product. In addition, you must not use ultrasonic cleaning in the diamond shop. Non-professional emerald jewelers do not have professional emerald maintenance knowledge. If the ultrasonic cleaning method using conventional diamonds is easy to cause the emerald to break, you can also use baby oil to maintain at home. .
