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. Emerald is a very old gem, which was used as jewelry in ancient Egypt.
Berylline is English, which comes from the Greek beryllos (emerald) and gradually evolved from the Latin beryllos.
Emerald in English comes from Persian zumurud (emerald), and later evolved into Latin smaragdus, which was misrepresented as esmeraude and emeraude, and later became an English spelling form. Chinese is transliteration. Tao transliterated as "supporting the wooden thorn" in his "Dropping out of Farming". The old fashions in China have names such as "mother green" and "water-helping green". Hong Kong is also called "Lu Zongqing".
Emerald is one of the oldest gemstone varieties and was used as jewelry in ancient Egypt. Cleopatra (Cleopatra's name), a famous mine at that time, has been exhausted by a large number of mining.
Emerald is a rare and flawless gem. In fact, it can be said that there must be some cracks and inclusions in emeralds, and the types of cracks and inclusions are very complicated, even called "garden" by researchers.
Too many inclusions will naturally affect the value of gems, but for gem researchers, the inclusions of emeralds are rare samples. By observing different inclusions, we can distinguish different origins and growing environments of gems.
Although the inclusion of emerald greatly affects the beauty of gemstones, its beautiful green color is still incomparable to other gemstones. The green color of emeralds comes from chromium ions, which can be observed by Charles filter.
Under the Charles filter, most emeralds will appear dark red due to the existence of chromium ions, while most other green substitutes will appear dark green. This rule can only be used as a reference for identification and cannot be used to judge whether it is true or not, because some African emeralds are not red under the color filter, on the contrary, some artificial emeralds are strongly red.
