Emerald is said to be able to protect the wearer from calamities, it has a really long history, and is one of the most valuable gemstones due to its mystical green that can calms the mind. Emerald has thousands year long history, its name originated from the ancient Greek term “smaragdos”. The legendary Cleopatra Mine (Egypt), which location is confirmed in 1818, was said to produce the pale translucent emerald in the ancient time. However, in the end of 16th century, when the Colombian emerald was brought into Europe, the history of emerald was drastically changed. The large and beautiful emeralds that were widespread from Mexico to Peru, were brought home by the Spain colonist to worked them into cabochon cut, beads cut, or even crafted them into sculptures, and offered to the royals of Europe, Turkey, Iran and India. The emeralds that were called Spanish emerald or Peru emerald in Europe were actually produced from Colombia. Colombian emeralds are well known for their gentle and austere green. Although there are secondary blue and yellow hue mixed in it, but it is still close to pure verdant green, and doesn’t have grey which will lower the hue. In term of its color, the green in Columbian emerald is due to the trace amount of chromium, while the green in emerald from Brazil and Zambia is due to the vanadium, this different in the element also cause the green hue to distinct. Even among the Colombian emerald, the emerald from Muzo mine possess exceptionally gentle color, compared to the other most precious color stones like sapphire from Kashmir and ruby from Mogok, emerald is also the most expensive in comparison of gem quality in 0.5 to 2 carats. It is even said to be more expensive than a round brilliant cut diamond polished from a high-quality raw ore. However, emerald is said to have the most fissures. There are very few fissures when the beryl is still colorless, but when impurities like chromium or vanadium is mixed in and forming the green color, it causes tension during crystallization, forming the fissures in the emerald. To deal with the fissures, most of the emeralds will be soaked in colorless oil or resin, this is called impregnation. By doing so, the colorless oil or resin will fill up the small gap of the fissures that reach the surface from the internal, enhancing the beauty of the gemstone. There isn’t much issue with the impregnation for make-up purpose as it has been done for few hundred years, but gemstone that underwent high degree of impregnation may looks good at first glance, but the fissure may become more apparent and lose its beauty. Therefore, the size of surface fissures is decisive for the value of emerald.
