What is Emerald ?

Definitions of emerald :

Emerald is a green to greenish blue variety of braille, a mineral that contains aquamarine as well as braille in other colors.

Emerald means green. Emerald hardness is 8-7.5. Emerald is a braille species with a crystalline and very beautiful color and is also found in green, blackish green, whitish green, and yellowish green.The beauty of emerald color is related to the chromium and vanadium in it.Emeralds usually contain impurities that are very useful for distinguishing natural from artificial emeralds.

Gem experts differ on the degree of green, which turns one stone into emerald and the other into cheaper green braille. Most gemologists, gemological laboratories, and sellers of colored stones classify green stone braille when it is "too light" in color so that it can be classified as emerald. However, even within that group, there is disagreement about what is considered "too light."



Types of emeralds and its sources :

The index of emeralds is Colombian, to which the most famous emeralds belong. Colombia is one of the top emerald producing countries in South America. There are about 150 known emerald reserves in the country, the most important and famous of which are the Muzo and Chivor mines, which were mined and mined in the past by the Inca civilization. Colombia's most economically important mine is the Coscuze mine, which produces approximately three-quarters of Colombia's emeralds. Colombian emeralds are completely different from the emeralds of other countries and it can be said that the best and most colorful emeralds belong to Colombia. In addition, very rare emeralds are sometimes extracted from the country's mines, called trapiche emeralds, which emit six beams from the center. Undoubtedly, the origin of the best emeralds is the country of Colombia, but the place of origin of a stone is never considered as a guarantee for its quality. Other high-quality emeralds are also found in Zambia, Brazil, Zimbabwe, Madagascar, Pakistan, India, Afghanistan and Russia. Zambia, Brazil and Zimbabwe are well known for their international trade in high quality emeralds. The color of these emeralds is darker than Colombian varieties, they have a blue undertone. High-quality emeralds in small sizes with very vivid colors and yellow undertones are extracted from the famous Zimbabwean mine called Sandavana. Brazil, which borders Colombia, also mines beautiful green emeralds from the Nova Era mine, where very rare cat-eye and six-pointed star emeralds are mined. Today, thanks to emeralds found in African countries and Brazil, the amount of emeralds in the market has increased, which has pleased the lovers of this gem.



History of Emerald :

The ancients believed that this gem brought purity and decency to its owner, protecting him from evil spirits. In ancient Greece, emerald was highly respected, but in Rome it was less considered and seldom used. In the Emerald Torah, one of the cornerstones of the city of Jerusalem is introduced, so it has a special value and closeness to the people of Israel. It should be noted that in the distant past, the original gems had a medicinal aspect rather than being used as ornaments, and doctors prescribed eating or purifying their powder and decoction. Emerald in particular was considered more medicinal and healing than other gems. For example, emerald decoction was prescribed to treat cancer or epilepsy, as well as to treat dysentery. Greek physicians believed that powdered and burnt emerald smoke was used to treat snakebites, colds, and shortness of breath. Before the spectacles and magnifying glasses were made, a cut emerald was used to study and see small objects, and it was called a study stone. In some cultures, emeralds are the customary gift for the fifty-fifth wedding anniversary. In some other human cultures, emerald is also used as the gem of the twenty-fifth anniversary of marriage. Emerald is considered the birthstone of May.

Emerald has had many names throughout history because it was a stone that was valued by all the great ancient empires. In ancient India, this stone was known as "marakata" which means "green plant". The modern name emerald is probably derived from an ancient Persian word that translates to Latin as "smaragdus". Eventually the word turned emerald.

Emeralds were sold in ancient markets in Asia and Europe as far back as 6,000 years ago. On the other side of the world, the Incas worshiped the precious green emerald.Emerald’s lush green from ancient times has soothed souls and excited the imagination. Rome’s Pliny the Elder described emerald in his natural history, published in the first century AD: "... nothing greens greener" was his warrant. Even Aristotle mentioned emerald in his writings and said that emerald can relax and soothe the eyes and also improve one's condition.



Emerald lathes :

While the high hardness of emeralds (7-5-8) largely prevents scratches on this precious gem, its brittleness makes it relatively difficult to cut, mount, and clean due to cracks. Even for a skilled lathe operator, emerald lathe is a difficult task. First, because of the high price of raw crystals, and secondly, because of the inclusions. They use gems. Emerald lathe or rectangular lathe, which is basically one of the stepped lathe designs in which the corners of the emerald are decorated with plates which, in addition to intensifying its beauty, increase its resistance to mechanical pressures and physical factors. Emeralds are also cut in other ways, and if the raw crystals contain a lot of impurities and impurities, they are considered to be cut into dimples (it is a hemispherical cut made with circular or oval bases and most used for a ring). has it).



The value of emeralds :

Like many stones, the price per carat of high quality emerald increases rapidly with size. for instance, in a recent price guide, high-quality 3-ct Colombian stone was mentioned three times as much as six times more valuable than quality 1-ct stones.

Value factors depend more on emerald color, and subtle differences in saturation and color affect the price significantly. The most desirable emerald color is slightly bluish green with a medium dark tone with strong to vivid saturation.

Clarity is significant, but inclusions are tolerated more in emeralds than practically any other gem. High quality, unenhanced stones (with certification) can cost up to 50% more than treated stones of the same size, color and clarity.



Synthetic Emerald :

synthetic emeralds were first produced in the mid-1800s, but it was not until the 1930s that Carol Chatham produced artificial emeralds on a commercial scale. After commercial production began, syntheticemeralds were regularly introduced to the market. Today, several companies, including Chatham Created Gems, Gilson, Kyocera Corporation, Lennix, Seiko Corporation, Biron Corporation, Lechleitner, and Regency, produce synthetic emeralds using flux and hydrothermal processes.

synthetic emeralds, commonly known as laboratory emeralds, have the chemical composition and crystal structure of natural emeralds and are sold alongside natural emeralds in most gold shops. When compared to natural emeralds, synthetic materials usually have a clearer appearance and appearance than natural stones at an equivalent cost.

synthetic emeralds or any type of synthetic stone of any kind must be clearly declared to the buyer. In this case, they are another option for the buyer. Many consumers get a superior look when they buy synthetic emeralds at a significantly lower cost.

The key points for distinguishing natural emeralds from synthetic emeralds are refractive index and magnification. Natural emeralds generally have a refractive index that is slightly higher than most hydrothermal-produced synthetic emeralds and is actually higher than most fluorinated synthetic emeralds. These differences are not large enough to be trusted to be recognized. However, they can be used as a valuable indicator.

Magnification is the most important factor in distinguishing natural emeralds from synthetic emeralds. synthetic emeralds can be identified because they contain visible properties that are the product of techniques created. synthetic hydrothermal emeralds may have characteristics such as: Chevron growth zone, head nail spines, and small gold components. Flux-grown emeralds may exhibit properties such as wispy veil inclusions, small platinum crystals, or parallel growth plates that many gemologists can microscopically detect most synthetic emeralds.

How is an Emerald Cut :

Emerald cut apart from the color is the main factor determining its value and beauty. Emerald is a durable gemstone but at the same time it is one of the different shapes and sizes of carats. Various factors are considered when making emeralds from a rough deposit. Today, emeralds are typically cut using technology-based cutting that ensures precision and beauty. Rugged emeralds come in a variety of shapes and sizes. Some are found inside a mineral, while others are isolated from the rock and found in alluvial form (such as smooth pebbles). After extraction from the mineral, various considerations are considered for the production of high quality emeralds.



Shape and Carat :

Emeralds can be cut into different types. Common shapes include cushion, round, emerald and princess. Emerald is fashionable in all forms of popular diamonds. However, the main difference is that emeralds have a heavy carat weight at the bottom of the gem. This means that the top face and the millimeter size of the diamond with the same carat weight look slightly smaller. Emeralds are cut to calibrated sizes according to their shape. These common sizes allow jewelers to create jewelry designs in widely accepted emerald sizes.

An emerald cutter understands the best shape that can be made from rough stone, given its overall shape. The overall goal is to create a shape that prevents emeralds from being wasted and uses the maximum amount of uneven gemstones. Round emeralds are popular and cause more rough waste when produced so they can have higher premiums.

Other shapes, such as emeralds and cushions, are used to make engagement rings. Emeralds are also slaughtered in the form of emeralds, the structure of the emerald crystal can best be cut in the form of emeralds. This cut also creates the least amount of loss and gives stability to this gem. In addition, emeralds have a deep and rich green color that is beautifully represented by the open view of the emerald gemstone.



Types of Cuts

·       Step Cut : A stepped or emerald cut is popular and has been specifically named emerald gemstone. It has parallel sides that are cut exactly from top to bottom. This makes the emerald color look bright and also helps the emerald maintain its structural integrity. Avoid emeralds that have large inclusions at the top, as they are more visible.

·       Brilliant Cut : It is a brilliant cut that has triangular cutting faces and varies in number depending on the shape of the emerald. It is difficult to produce a brilliant cut because it requires more precision and potential loss. However, it creates the most shine.

·       Mixed Cut :Mixed cut is a combination of shiny cut and stepped cut and this cut is usually used for emerald. The emerald crown is usually wasted in glossy cuts to increase shine and stepped cut booths to minimize wasting. Jewelers use emeralds that have a shiny or mixed cut to maximize shine and color.

·       Cabochon Cut :Cabochon Emeralds are round with a smooth exterior. Cabochon emeralds are more affordable than other cuts because they are easier to produce than other cuts. Cabochons are produced in different sizes.



Emerald Inclusions

Most emeralds contain inclusions that occur naturally during formation on Earth. These compounds create a distinct identity for each natural emerald. Because of the emerald green color and silky compositions like it, inclusions are often known as "jardin". A cut should ensure that the mixtures do not interfere with the appearance and attractiveness of the emerald. Many of the components appear opaque, dull, lifeless and devoid of luster. In addition, the color will not be so vibrant. Clearly ensures that all emeralds used are eye-clean and have minimal visible inclusions.



Emerald Size

Emeralds are cut lengthwise and measured in millimeters, not carats. The carat weight is greater than the approximate size of the emerald. To display the emerald color, it may be cut deeper or shallower, the weight of the carat is strongly affected, even if the length and width of the shape are the same. As the size of the emerald increases, the price increases exponentially. Round and octagonal emeralds appear larger than other emerald shapes. Cushion and princess cuts look the smallest. Squarer shapes tend to distribute more size and weight deep in the gemstone. In diamonds, a manufacturer may reduce the size to eliminate inclusions. This is rarely the case with emeralds because the ingredients are found in natural emeralds.



Emerald Clarity

Emerald is one of the most valuable gemstones available. All emeralds have minor imperfections known as incisions and may be visible without magnification. Emerald inclusions include clouds, needles, crystals, feathers, dots and holes. This components occur naturally during the emerald growth process. There is no standard grading scale for clarity in emeralds. They are simply combined with color on the AAA rating scale.

Since the inclusions are found in all emeralds, it is recommended not to worry too much about seeing them in higher qualities. Color is the main factor in determining the quality of emerald. However, very large emeralds will lose color due to inclusions. In this case, the quality of emerald is reduced.

The Clarity of emerald, like its color, is assessed without magnification. The main thing is to pay attention to general clarity instead of focusing on inclusions. The most common components are small cracks or fractures that look like wavy or whitish lines inside the emerald.



Emerald Color

The biggest factor for the value of an emerald is its color. Emerald is evaluated and graded based on color, color and color saturation. These three elements ultimately determine whether emeralds are of AAA (highest) or C (lowest) quality. While color evaluation is subjective and there is no industry standard, AAA, AA, A, B, and C are graded, but emeralds are green, but many may be yellow, blue, and brown. Have. The purer the green, the higher or better the quality of the stone. The emerald color is evaluated without magnifying by observing the Gemstone. To see the color, it can be twisted and tilted in many ways. Ideally, green would be the color without the extra color. In the ideal emerald, its tone is vivid and deep, not too dark and light.



Color Consideration

Very precious emeralds have a pure green or one of those in which there is a blue color. In addition, those that are evenly saturated and have a medium green color (not too dark, not too light) are very valuable. A slice also checks that the green is evenly distributed throughout the gemstone to make the emerald look alive and shining in all respects. All emeralds with Clarity and a uniform color and light green are selected that are neither too dark nor too light.



Emerald sources

Emerald extraction is an interesting process. Emeralds are usually attached to other rock formations and are not found as an independent rough gemstone. Emerald extraction is often done by hand because technology and machinery can put heavy pressure on the rock and separate the heavy emeralds. Typically, emeralds are extracted and the stones are divided into pieces. These pieces may or may not have emeralds (natural braille) and are transported for removal and eventual manufacture.

Clarity emeralds are commonly mined in Colombia, Zambia and Brazil. It is known that each region produces high quality emeralds with fewer inclusions and a clearer green color (less background). In some cases, the origin of emeralds can even be identified by color. Emerald mining is an important support structure for cities around the world. Mining investment supports schools, public facilities and hospitals.

Emerald is a common option for diamond engagement rings. Apart from being unique, they are a complex, rich and royal gemstone. Because emeralds are rarer than diamonds, they are not a cohesive source of controversy. This is great because it ensures your gemstone is conflict-free and your love is not contaminated.
