Emerald identity card

The emerald comes from the Béryl family, just like the Aigue-Marine. It is an aluminum and beryllium silicate which has a hardness between 7.5 and 8. Its trademark is its crystallization: its irregularities come from the process of its formation, according to the mines and the continents of its origin. The emerald is one of the rare gems to give us as many answers as to its exact origin. His inclusions so characteristic and omnipresent provide him with a very particular charm, which we sometimes speak of" garden "To identify it and define your place of birth. Few are the emeralds without visible inclusions. . In the raw state, the emerald generally appears in the form of a hexagonal prism. The famous"Emerald size",Rectangular in shape and in front angles, also follows the shape of its elongated raw crystal. When the emerald contains too much inclusions, it is not uncommon to see it cut in cabochon.Marélie ringin yellow goldcreator Philippe Tournaire.

Treatment and imitations of the Emerald

The vast majority of natural emeralds present micro-fractures and many inclusions which can sometimes make stone less transparent and therefore less attractive. To alleviate these effects, it is often imbued with an oil or even a colorless resin. The majority of emeralds are thus embellished by this process.

It is a gem that you have to clean with caution. The emerald being particularly recognized, many laboratories have sought to imitate it, using materials such as glass or by assembling for example two synthetic spinels or two colorless beryls on both sides of a layer of green glue ,

Giving the illusion of a single stone (these assemblies are commonly called doublets, triplets). As for the synthetic emeralds, it is a question of reproducing the stone from low quality crystals, by purifying and crystallizing them again.

This result can be obtained by artificially recreating the conditions for the formation of a natural emerald. Imitations are generally detectable because the stone seems too perfect, without visible inclusion, or because it has unknown inclusions of natural stones, such as gas bubbles for example. Syntheses require greater experience.

Color, major asset of the emerald

This is the color that constitutes the determining factor in the overall value of an emerald. We consider a beryl as an emerald when its color goes from green-yellow to green tinged with blue, with a rather pronounced tone and a strong intensity. This popular color is due to the presence of chemical elements such as chrome, vanadium and iron. The more it contains iron, the more it is nuanced with blue. Among all the known green stones, the emerald is queen because none has its equal in terms of color and history, although other gems are also very appreciated for their different greens.

For comparison, we find the peridot and tsavorite: just as we can refer to the emerald as being green" garden ", we associate with peridot the green of a meadow,

a lime or an olive because this stone is predominantly green but very often tinged with a more or less pronounced yellow. This luminous stone was baptized "Gemme du Soleil" by the Egyptians. Another stone called tsavorite is a particularly sparkling green garnet slightly tinged with yellow or blue, which is closer to the emerald than the peridot. Recently discovered, tsavorite is the best known of green grenats. In large part, the peridot and tsavorite owe their color and vanadium respectively ... Two elements that are also found in the emerald, with chrome! These three intense green gems each make their contribution to The creation of Tournaire jewelryExceptional, in colors full of life.

The emerald tells us its origins

Through its clarity and color, the emerald tells us its story. It was by being guided in the garden of its secrets that this sublime gem reveals its origins to us ... Historians believe that the first emeralds appeared in Egypt in 3500 BC. Egypt was the major source of emeralds until the 16th century. Then the Spanish explorers discovered abundant mines in South America ... where we find the largest world source of quality emeralds: Colombia. Nowadays, the majority of emeralds come from deposits in Colombia (Muzo, CoScuez, Chivor ...), Brazil, Zambia and Zimbabwe. Minor sources include Afghanistan, Pakistan, Australia, the United States and Russia.

Unlike many gems, you can easily know the origin of an emerald.

It is for this reason that these terms are commonly used:

The emerald "Colombian":She describes the most sought-after emerald, of a green-blue color with great intensity. It is from the emeralds of Colombia that the others are tried. One of the typical inclusions of chivor emeralds in Colombia is iron pyrite.

-The "Brazilian":Said of a clearer emerald than the others, with mica inclusions and other minerals.

The "Zambian":A little darker and blue than the "Colombian", generally with fewer inclusions

The Sandawana emerald: Intense green, very bright

Afghan emeralds:They often reveal clouds of black flakes and white crystals.

In addition to these inclusions revealing their origin, a reliable and advanced scientific study has made it possible to establish a real identity card for each of the main mines of emeralds. Researchers have indeed managed to define the origin of the emeralds by analyzing their surface, without altering them. This discovery thus made it possible to precisely trace the history of these mythical stones.

Rich in its history, its fractures and its color, the emerald is a full -fledged gem that has never stopped seducing the whole world. The creative craftsman Philippe Tournaire likes sparkling stones of beauty, full of hidden treasures that only ask to be revealed in broad daylight by highlighting them in aoriginal creation. Both singular because of its particularities and common because known to all, the emerald has distinguished itself from other green stones that nature offers us to contemplate.

A real garden alone, it deserves to be visited and revisited!
