Green is the color of nature which lives and breathes straight through the green leaves, and the green grass in the surging meadows. Green is also the color of our gemstone emerald. In fact emerald is the only gemstone to have a color named after itself 'emerald green'.
Emerald Bracelet Gold
The name Emerald stems from the Greek word smaragdos straight through the old French Esmeralde, which just means 'Green Gemstone'.
Emerald is a collection of the mineral Beryl which has the chemical recipe of Be3Al2(SiO3)6 (beryllium aluminium cyclosilicate). Pure Beryl is colorless and Emerald gets its beautiful green color from the touch of impurities of chromium (or less frequently vanadium) in its molecular structure.
Emerald has been known to mankind and treasured as a gemstone since old times when they were found only in Egypt. The Egyptians from the time of Cleopatra excavated it under the blistering desert heat and fear of poisonous snakes and scorpions. But close to the year 1492 onwards they began to turn up from other regions of the world.
Today they are mined almost all over the globe in Brazil, Pakistan, Zimbabwe, Zambia, Russia and Columbia. The best stones come from Columbia but the most indispensable emeralds came from Rajasthan region of India in the 16th century. All the leading jewelry makers like Cartier, Bvlgari and other secure much of their emeralds from India.
Akin to all gemstones, the attributes which decide the capability of an emerald and its worth are Color, Clarity, Cut and Carat weight.
Its color establishes the capability of an emerald far more than anyone else.
Color:
Quality emeralds are deep rich grassy green and effervescent in color while lesser emeralds are paler and less brilliant. There are added elements within the color factor which have to be given observation like the hue of the stone together with tints other than green; the tone of the color ranging from dark to light shade; and saturation meaning the purity of the color and the level of the mixed secondary hues. Yellow and blue, the hues found adjacent to green on the spectral color wheel, are the typical secondary hues seen in emerald.
Clarity:
The same gigantic geological soldiery and pressures that aid the formation of emeralds also lead to fissures and inclusions in the gemstone, and pretty much all Emeralds come with inclusions and fissures. It is incredibly rare to come over an emerald that is entirely clear and such a gemstone commands a heavy premium. At the same time a fully clear stone makes it presuppose of being a manmade one.
Unlike diamonds which are scrutinized under ten times magnification to locate inclusions, an eye clean emerald with inclusions not descriptive to the naked eye is carefully flawless. But connoisseurs prefer emeralds with at least a few inclusions as an evidence of their authenticity.
A few inclusions are incredible and do not detract from the value of the stone as much as with other gemstones and emerald ranks among the top precious gemstones of the world in spite of the flaws and inclusions.
However, you should make sure that fissures do not go too deep into the stone weakening it and production it prone to splitting.
Emeralds are commonly treated by plunging them in colorless oil or resin to fill up its fissures and greatly enhance its clarity and durability. It is an acceptable practice in gem trade as long as it is openly declared.
Cut:
An Emerald should be well cut to give it the optimum glow and sparkle though the cut is not as leading in case of an emerald as with other gemstones since the emerald is mostly valued on the basis of its color. Moreover, an emerald is commonly too included to sparkle.
However, it is still imperative to know the discrepancy in the middle of a good and a bad cut to be able to make an educated choice.
In a well cut emerald you should not be able to look though the stone but rather the light should be reflected back at you. You should keep away from emeralds with uneven facets. Turn the emerald around, and verify that each facet reflects light like a well polished mirror with no rough or dull blemishes.
Due to the natural inclusions, cutting an emerald is a difficult task for every craftsman. The shape "emerald cut" which is popular now for diamonds as well as other gemstones was in reality originally designed for emerald. It is a rectangular or quadrilateral cut with cut corners. The facets are broad with flat planes resembling the steps of a stair. This cut brings out the magnificence of this indispensable gemstone to the the best inherent and at the same time safeguards it during an unintentional impact.
The cabochon cut is another type of gemstone cut given generally to emeralds. Its relative crystal non-uniformity makes emeralds more likely than other gemstones to be cut into cabochons, rather than faceted shapes.
Carat:
Emeralds of big carat size are very rare production the larger carat size stones very high-priced. Price changes drastically with puny discrepancy in weight which is why emeralds are puny to few acceptable shapes. The volume lost in cutting would lead to loss of value.
A very rare type of emerald known as the 'Trapiche Emerald' set apart by star-shaped rays originating from its town in a hexagonal pattern is found only in the Muzo mining district of Colombia. The phenomenon is caused by black carbon impurities that happen to form in the same star shaped pattern.
Man made emeralds are also produced today by simulating the atmospheric conditions conducive to formation of emerald in a lab with certain elements.
Don't clean your emerald whether with hot soapy water or steam or in an ultrasonic cleaner because the oil or resin used in treatment could be removed or broken, production fissures more noticeable. Luckily, it is inherent to have emeralds re-oiled. Emeralds are durable gemstones with a hardness of 7.5 to 8. Nevertheless, emeralds should generally be treated with care and protected from accidental clashing with other objects.
Use a tender brush and a very mild dish soap to clean your emerald.
Cleopatra's love for emerald was legendary. Mummies in old Egypt were frequently buried with an emerald on their necks, the victorious green a symbol of eternal youth. The Mogul emperors of India, together with Shah Jahan who built The Taj Mahal, fancied emeralds so much they inscribed them with sacred text and wore them as lucky charms. another mogul emperor Jahangir owned a drinking cup carved out of emerald.
Emerald is regarded as the customary birthstone for May, as well as the customary gemstone for the astrological signs of Taurus, Cancer and sometimes Gemini. In some cultures, the emerald is the customary gift for the 55th wedding anniversary.
