Color: The color of emerald is more than color, but more gloss. The color of the emerald is mainly the best in green and blue, but there is gray in addition to green, but the emerald quality of this color is poor. Therefore, the emerald is better in green and blue, and the green is gray.
Transparency: Choosing a high-quality emerald certainly requires high transparency, with the clearest texture as the best variety, and translucent as the common variety. Of course, there should be no impurities and some inclusions, and if it is pure, it is a rare high-quality emerald.
Purity: The interior of emeralds often has some inclusions (envelopes), such as pure ones, which are rare top grades, while low-priced emeralds generally have poor clarity.
Cut: The quality of the cut will affect the gloss of the whole piece of stone. The emerald type is called the standard cut, and if it can fully display the emerald gemstone gloss, then it is a superb cut.
Weight: Generally, the crystals of emeralds are not large. After cutting, the quality is excellent, and the weight is more than 2 carats. It is rare. If the weight is more than 5 carats, it is a rare treasure. Therefore, the heavier the emerald collection, the higher the value, the better the quality, and the quality will be excellent after cutting.
