Emeralds, rubies, sapphires and diamonds are also called the four great gems, and among emeralds, emeralds are the most precious and have the title of "king of emeralds". Generally speaking, emeralds symbolize self-confidence, kindness and luck. It is also recognized as the 50th wedding anniversary stone in the world jewelry industry. Emerald has a long history, which can be traced back to ancient Egypt, when it was already a precious jewel.
The English word emerald is transliterated, and the original text is translated as "holding the wooden thorn". Later, there was a translation of "Zi Mu Lv", and it took a long time to get the name of Jade. It is because of this name that everyone thinks emerald is suitable for the elderly to wear. This is a complete rumor, but now emeralds have really become the best choice for giving jewelry to the elderly.
In the history of our country, emeralds were not valued until the Ming and Qing Dynasties, especially in the Ming Dynasty, when an emerald must be embedded in the crown symbolizing the throne. Emerald is precious, but it is difficult to be perfect. Every emerald will have some cracks and even some impurities, but it is this imperfect characteristic that makes emeralds more popular with everyone.
The color of emerald is very special. Its green is a kind of saturated green, with a touch of softness in the rich color, which is the greatest charm of emerald. Emeralds are green because they contain chromium oxide, which is an oxide. Although the content of chromium oxide is very small, it just makes the color of emerald just right.
