A jewel in the lush green of the depths of the rainforest: the Emerald

The Indian Mahardschas were already under the spell of the dark green emeralds, which kept it in its treasure troves. They believed that the adorable sparkling gems help to health and happiness. Likewise, Kleopatra Queen of Egypt was especially attracted to emeralds and had even their own Emerald mines.
The Emerald has received because of its distinctive color based on the Greek word for green stone, smáragdos, its name. Originally this term goes back to the Semitic barraqtu , which can be translated as brilliant, flashing stone . This is very true for the Emerald, which is characterized by its glassy luster.

These are trusted organizations that issue such certificates for coloured gemstones like Emerald, GIA (Gemological Institute of America), the AGL (American Gemological laboratories), as well as the GRS (Gemresearch Swisslab). As for coloured gemstones still no generally binding standards have prevailed, as is the case with diamonds, the certificates of various testing institutes slightly in their design and in the designation of the quality levels differ.
It is common to all, that they put a strong focus on the colour grading of gems. The most valuable are emeralds in a strong green colour of medium brightness; According to the system of the GIA, such a color would be known as “vivid, medium dark green”, at the AGL, however, as “very good, medium dark green”.
The Emerald and its characteristic color: the emerald green
All green Beryls are referred to as Emerald; their color range a pure green from a yellowish green through to a bluish green. It is typical of this gem, that he considered adopts slightly different shades from different angles, what is called Pleichroism .

The Emerald – Colombia as the most important mining area
The by far most important Emerald deposits are spread across Colombia, where already the Incas gems from the mines in the vicinity of Bogotá, Muza and Chivot. The Colombian emeralds are characterized by their beautiful, vibrant green and the exposure of its inclusions.
In addition, Brazil has about large Emerald deposits and the gems found there characterized usually by their above-average purity, even if they are usually lighter in color than those from Colombia.
Mid-20th century emeralds were also found in Zimbabwe, which although is relatively small gems that shine but due to their excellent quality.
Other, less significant occurrences are located all over the world, such as Australia, China, India and in the Ural mountains.
The Emerald – impurities (called Jardin) as a characteristic feature
The Emerald is one of the gems of purity type III, which means that inclusions and fine cracks at it are the rule and perfectly transparent pieces represent the absolute exception case. The impurities but not necessarily negatively affect the value – assuming, of course, that they are not too flashy and not significantly affect the appearance and durability of the Emerald. In the jargon, these internal features bear the name Jardin (from French) ( jardin garden =). The purity of an emerald is different than a Diamond , not under the microscope at tenfold magnification. The gem is regarded here as a pure, if no inclusions are to see with the naked eye.
In rare cases, an cat’s eye effect can occur when a troubled emerald — in this case a narrow slit-like strip of light is on the surface of the gemstone.
A form developed for the Emerald: Emerald cut
Specifically the Emerald a cut form was created for, which was named after him: the Emerald cut. Here the gemstone has a rectangular base with truncated corners, which is especially for the inherently brittle emerald is protected in this shape well against damage.
In addition, many more cut forms are used as the drop cut or the oval cut. Also the brilliant cut is ideal for a very transparent and translucent Emerald.
Heavily clouded stones are cut usually to a cabochon that is characterized by its smooth, curved outside surface.
The Trapiche Emerald: a Colombian special feature
Something quite extraordinary is a so-called Trapiche Emerald, in which several crystals together to form a shape that resembles a wheel with six spokes. Such an emerald is very rare and long time Colombia was the only country in which there are gems of this type.

The pricing of emeralds: Color as the most important criterion
The value of Emerald to a considerable extent depends on its color. This goes so far that an absolutely pure gem in a light green costs less than a subdued of inclusions in the popular emerald green.
Further criteria are the purity and the size of the gemstone. Because prices depend from numerous other factors, such as the shape, the quality of sanding and the symmetry, it is hardly possible to give specific figures. To understand the differences in price, you must look closely and be aware of all these issues.
You can serve as a clue, that is the price of a 0,5-karätigen emerald in a vibrant blue-green with the purity of SLYI (slightly included, with small inclusions) and very good cut on about 1,100 euro amounts. A similar one-carat stone in a lighter color costs not much more with approx. 1.300 euro.
In a beautiful medium-dark blue-green color and purity SLYI with very good cut an emerald can have a price of about 22,000 euros.
For an emerald in the imposing size of 15 Carat vivid green, the purity of the ECLN (eyeclean, pure) and very good quality of sanding, you must plan to the 50,000 euro.
