The most fascinating thing about an emerald is its beautiful green color, which has even earned its own name, emerald green, and is why the gemstone was chosen as the birthstone for the month of May. Color is the most important criterion for an emerald's value, with the highest reputation being given to a very intense and vibrant green with no grayish hue and a medium color brightness. The most beautifully colored emeralds are those from Colombia, where this green is most pronounced. Brazil is also an important source of good-quality emeralds, although these are generally somewhat brighter than Colombian ones. A characteristic feature of an emerald is its pleochroism, which manifests itself in the gemstone taking on different colors depending on the angle from which it is viewed.

The emerald – a gemstone in spring-like green
The Emerald and its History
The emerald has a long history. Emerald mines in Egypt, which may have existed as early as 3,500 BC, were only rediscovered in 1816 by the French mineralogist and explorer Frédéric Cailliaud. These mines in the eastern desert region probably supplied Europe with the precious minerals for more than a thousand years. But the Habachtal region in the Austrian state of Salzburg also produced one or two emeralds, and the discovery of Roman earrings also suggested that emeralds were found in the Mingora mine in Pakistan's Swat Valley.
Cleopatra's preference
The emerald, which, like aquamarine , belongs to the beryl mineral family, was already a popular status symbol in the time of the Egyptian pharaohs. Cleopatra already appreciated the gemstone with its unique color: she wore lavish emerald jewelry, adorned her home decor with them, and gave emeralds, inlaid with her image, to dignitaries of her empire. Thus, the gemstones held great significance for the Egyptians – they were not only beautiful to behold, but also patriotic symbols expressing national pride. For this reason, Cleopatra declared the impressive gemstone her property in her country around 47 BC. Since then, emeralds have been repeatedly associated with fertility, immortality, rejuvenation, and eternal spring.
The “Jardin” of an emerald – internal inclusions as fingerprints of nature
There is hardly a completely transparent emerald – impurities and cloudiness in the crystal structure are a hallmark of these gemstones. In terms of clarity, they are classified as Type III, in which irregularities and small cracks are almost always present. These characteristics are referred to in emeralds as jardin (= garden) in reference to the French word, and characterize the individual appearance of each gemstone. The clarity of an emerald is determined with the naked eye and not under a microscope like with a diamond . However, since the numerous inclusions can have a negative impact on the material properties of an emerald, a special cut was developed for this gemstone: the rectangular emerald cut. This cut is particularly suitable for emeralds because it has beveled corners, eliminating the risk of damage to the exposed areas of the emerald, which tends to be brittle.
The rare Trapiche emeralds from Colombia
Occasionally, an emerald may exhibit a unique intergrowth of different crystals, resembling a six-spoke wagon wheel. What's special about this variety is that the Trapiche emerald grows in a hexagonal shape from the beginning, rather than being shaped by a gem cutter. The name Trapiche is Spanish and translates as "sugar mill."
The Brilliance of the Emerald
In addition to the inclusions, another characteristic property of the emerald is its unique brilliance. Silky, warm, soft or green fire - this is how the shine of this gemstone is often described and is significantly influenced by color, clarity and cut. The quality of the cut is particularly important for emeralds, as the inclusions in the emerald that are visible to the naked eye can be placed in such a way that the beauty of the gemstone is not impaired.
