It's emerald green.
If you often watch TV dramas about the theme of the Republic of China, you may notice that under the elegant posture of those noble wives, they wear gorgeous makeup and expensive jewelry, showing the luxury and prosperity of the upper class everywhere.
One of the most common and expensive is emerald. Whether it is a solemn emerald ring or an earring necklace with classical temperament, it can perfectly set off the unique temperament of the wearer.
Emerald is called "the king of emeralds" by gem collectors, which shows its value and status. No green gem can compare with emerald, which is one of the four precious gems (red, blue, emerald and diamond) recognized by the international jewelry industry.
Emerald symbolizes kindness, self-confidence, kindness, eternity, luck and happiness. Wearing it will bring peace to people's life. This is also the 55th wedding anniversary stone. Therefore, it is favored by westerners with its unique green color, unique charm and magical legend.
Emerald is a very old gem. According to historical records, it is the earliest gem used as jewelry in the world. It was used in jewelry as early as ancient Egypt.
The color of emeralds is very charming. Some people use spinach green, onion heart green and tender tree bud green to describe it, but they can't accurately express its color. Its green color is very complex and diverse, with a little yellow in it and a little blue. Even the spectrum seems to be missing a point wavelength. Whether it is cloudy or sunny, whether it is under artificial light or natural light, it always emits soft and rich light.
Emerald is mainly produced in South America (Brazil, Colombia), Africa (Zambia) and South Asia (Afghanistan). Among them, the most important producing area is Colombia. It represents the highest quality and the longest history of origin and has always been synonymous with top emeralds. Therefore, in the field of collection, Colombian emeralds with less output and better quality are more worthy of investment and collection.
Color is the clothes she wears for emeralds. The most important factor to evaluate emeralds is its color, followed by purity, cutting, size and so on.
Emerald is called "garden gem" by scholars who study it, because it has many cotton and cracks, just because the interior scene is diverse, just like a garden. In fact, emeralds are very brittle, and naturally there will be many cracks, many of which need oil protection. Even if the original stone is dug out, it will be soaked in turpentine and needs oil protection when cutting. Therefore, oil-free pure emeralds rarely appear. If it appears, and it is relatively large, it is estimated to be sky-high or artificially cultivated emeralds.
Because cotton cracking is a common phenomenon of emeralds, buyers will basically focus on the color of emeralds. The price of a bright green emerald may be 100 times higher than that of a light green emerald.
To buy emeralds, you must first have a certificate, which is equivalent to the identity card of emeralds. Common international jadeite certificates include GRS, guild, IGITL, etc. Of course, SSEF and GGL, two top appraisal institutions, are also indispensable.
Among all the green gems, emerald is the most popular: crystal clear emerald with good brightness and saturation.
Most international organizations evaluate the color of top jadeite: bright green. Still intentionally green.
Guild laboratory named green as the better color in bright green.
Emerald crystals are generally cracked and mixed with impurities. These defects will still exist after cutting into bare stones. Therefore, emeralds are different from diamonds and cannot pursue high purity.
In fact, gemologists are very fond of emerald inclusions and call them emerald gardens. Different inclusion characteristics can reveal the geological environment and mineralization reasons of emerald formation, and reveal the source and formation time of emerald, which is an important basis for gemologists to judge the origin.
In order to improve emeralds, people invented the method of oiling. Colorless oil injection can effectively improve the purity of emerald, which is a recognized optimization method. But injecting colored oil or even filling resin is not recognized as a treatment method.
Among them, the emeralds produced in Colombia are called industry standards, and the two most important emeralds, Muzo and Chivor, account for about 80% of the total output of high-quality emeralds in the world. Among them, Muzo has produced countless world-famous emeralds and become a temple in the eyes of gem experts and collectors.
In a word, emerald is a precious gem. You need to fully understand the relevant knowledge of emerald before buying, so as not to be deceived!
