What is emerald? What is the basic nature?

How to evaluate the quality of a gem?
The definition of the quality of a gemstone is difficult to give, because so far the international standard has not been able to unify the evaluation criteria for color. The more common view is that a single gemstone with a large weight, good color saturation, and a small number of gemstones is good. .
Why are there no certificates for gemstone goods?
Because there is currently no uniform set of colored gemstone grading and evaluation standards in the world, and it is not possible to do detailed grading like diamonds, it is impossible to classify existing colored gemstones. Therefore, our gemstone products are not equipped with certificates.
The gemstone has been worn for a long time, why is there a dim phenomenon?
There are usually two reasons why gemstone jewelry has been worn for a long time:
1>, wearing reason: the jewelry will inevitably be contaminated with some dirt during the wearing process. Most of the goods are now made of 18K gold hollow claw setting process. Therefore, after wearing for a period of time, the dirt will accumulate in the hollowed out part, resulting in the color and gloss of the goods are not as good as before. Therefore, it is recommended that the gemstones purchased by the customer should be cleaned regularly.
2>, precious metal reasons: After a long period of wear, the K gold part will have different degrees of wear and discoloration, which will also affect the color appearance of the gem.
Gemstone maintenance
The way to clean and maintain the gemstone is roughly the same as that of the diamond. It should be stored separately in a jewelry box or a transparent plastic bag, and the ornaments should be prevented from colliding with each other.
To clean the gemstone jewelry yourself, place the gemstone jewelry in a diluted soap solution, gently rub the diamond and the holder with a soft brush, then rinse with water, then dry the water with a soft cloth, and don't forget to use the pot beforehand. Wash or wash the wash basin to prevent the gemstone jewelry from falling into the drain. It is important to note that emeralds should not be washed in an ultrasonic machine and should not be washed with strong soap or hot water to prevent tarnishing. In addition, emeralds are quite brittle, so be careful when wearing them to avoid impact.
