Emeralds

Mining ceased with the discovery of the Colombian deposits; only ruins remain. Since the onset of concerns regarding diamond origins, research has been conducted to determine if the mining location could be determined for an emerald already in circulation.

Traditional research used qualitative guidelines such as an emerald's color, style and quality of cutting, type of fracture filling, and the anthropological origins of the artifacts bearing the mineral to determine the emerald's mine location.

More recent studies using energy dispersive X-ray spectroscopy methods have uncovered trace chemical element differences between emeralds, including ones mined in close proximity to one another.

American gemologist David Cronin and his colleagues have extensively examined the chemical signatures of emeralds resulting from fluid dynamics and subtle precipitation mechanisms, and their research demonstrated the chemical homogeneity of emeralds from the same mining location and the statistical differences that exist between emeralds from different mining locations, including those between the three locations: Muzo, Coscuez, and Chivor, in Colombia, South America.

Both hydrothermal and flux-growth synthetics have been produced, and a method has been developed for producing an emerald overgrowth on colorless beryl.

The first commercially successful emerald synthesis process was that of Carroll Chatham , likely involving a lithium vanadate flux process, as Chatham's emeralds do not have any water and contain traces of vanadate, molybdenum and vanadium.

Gilson's emeralds are usually grown on natural colorless beryl seeds, which are coated on both sides. Hydrothermal synthetic emeralds have been attributed to IG Farben , Nacken, Tairus , and others, but the first satisfactory commercial product was that of Johann Lechleitner of Innsbruck , Austria, which appeared on the market in the s.

These stones were initially sold under the names "Emerita" and "Symeralds", and they were grown as a thin layer of emerald on top of natural colorless beryl stones.

Later, from to , the Linde Division of Union Carbide produced completely synthetic emeralds by hydrothermal synthesis.

According to their patents attributable to E. Flanigen , [28] acidic conditions are essential to prevent the chromium which is used as the colorant from precipitating.

Also, it is important that the silicon-containing nutrient be kept away from the other ingredients to prevent nucleation and confine growth to the seed crystals.

Growth occurs by a diffusion-reaction process, assisted by convection. Many synthetics are also UV inert. Synthetic emeralds are often referred to as "created", as their chemical and gemological composition is the same as their natural counterparts.

The U. Federal Trade Commission FTC has very strict regulations as to what can and what cannot be called a "synthetic" stone.

Emerald is regarded as the traditional birthstone for May as well as the traditional gemstone for the astrological sign of Cancer.

On one of Cortez's most notable emeralds he had the text engraved , Inter Natos Mulierum non sur-rexit mayor "Among those born of woman there hath not arisen a greater," Matthew which referred to John the Baptist.

The chief deity of one of India's most famous temples, the Meenakshi Amman Temple in Madurai , is the goddess Meenakshi , whose idol is traditionally thought to be made of emerald.

Emeralds occur in hues ranging from yellow-green to blue-green, with the primary hue necessarily being green.

Yellow and blue are the normal secondary hues found in emeralds. Only gems that are medium to dark in tone are considered emeralds; light-toned gems are known instead by the species name green beryl.

In addition, a fine emerald will be saturated and have a hue that is bright vivid. Gray is the normal saturation modifier or mask found in emeralds; a grayish-green hue is a dull-green hue.

Emeralds tend to have numerous inclusions and surface-breaking fissures. Unlike diamonds, where the loupe standard, i. Thus, if an emerald has no visible inclusions to the eye assuming normal visual acuity it is considered flawless.

Stones that lack surface breaking fissures are extremely rare and therefore almost all emeralds are treated "oiled", see below to enhance the apparent clarity.

The inclusions and fissures within an emerald are sometime described as jardin French for garden , because of their mossy appearance.

Faceted emeralds are most commonly given an oval cut, or the signature emerald cut, a rectangular cut with facets around the top edge.

Most emeralds are oiled as part of the post- lapidary process, in order to fill in surface-reaching cracks so that clarity and stability are improved.

Cedar oil , having a similar refractive index , is often used in this widely adopted practice. Other liquids, including synthetic oils and polymers with refractive indexes close to that of emeralds, such as Opticon , are also used.

These treatments are typically applied in a vacuum chamber under mild heat, to open the pores of the stone and allow the fracture-filling agent to be absorbed more effectively.

Federal Trade Commission requires the disclosure of this treatment when an oil treated emerald is sold.

Other treatments, for example the use of green-tinted oil, are not acceptable in the trade. These categories reflect levels of enhancement, not clarity.

A gem graded none on the enhancement scale may still exhibit visible inclusions. Laboratories apply these criteria differently. Some gemologists consider the mere presence of oil or polymers to constitute enhancement.

Others may ignore traces of oil if the presence of the material does not improve the look of the gemstone. Mining ceased with the discovery of the Colombian deposits; only ruins remain.
