If you are mosting likely to buy greater carat weight natural baltic amber, then you have to be supposed to see to it regarding its quality for the reason that enhancement as well as flaws can be easily checked out in rocks of big size.

A few of the dealers of natural ruby lay the prong upon the rock to hide the min imperfections in it and also they conceal the actuality that they in reality hid those some included imperfections to make sure that they can make even more amount of money.

That s why you need to keep in mind to buy loose as well as licensed or certified diamonds and if you want to gather it then you can do it afterward to ensure that you can be able to observe out the total diamond.

Prices of pink zircon differ as per its carat credibility hence, if you are monetary plan is reduced however you are setting up to go and also buy a 1 carat weight stone, then we advise you to opt for the 0.9-0.96 carat because of the reason that they likewise includes the similar top quality like color, quality, and also cut.

As a result of cut in the prasiolite green amethyst it seems great and gleaming that can be seen with the naked eye. Do not consider it as premium quality even if of its clear vision instead pay attention to its cut.

How these jewelers make out earnings?

The majority of people thinking that jewelry experts can effortlessly construct their earnings with the selling of artificial gems but the truth are various. They can t do it in this globe of competition. In addition it is also believed that the rock dealer can conveniently construct out revenue on the stone of larger size, alternatively this belief is not right. Jewelers usually construct out their revenue on the tool sized or smaller sized gems as contrasted to rocks of larger size.

 

Lab made gemstones have exact correspondence in Nature, have the same Chemistry, Crystal structure and equal Hardness to the corresponding Natural. In the following years other people with the same procedure were able to synthesize also: man made sapphire, colourless Corundum and other colors, lab ruby and Sapphires Asteria, etc .; the list is very long and to date the attempts and laboratory researches have not stopped, in an attempt to synthesize even the most complex gems.

 They insert the same chemical elements of a particular gem into some sophisticated equipment and reproduce (as much as possible) the same temperatures and pressures that normally occur in nature. There are today various methods to Synthesize Gems, some of which do not only reproduce the Color, Chemistry and Crystalline but they also try to imitate the characteristic signs that initially tended to distinguish syntheses from Natural gems.

The emergence of these synthesis methods led in the following years to other evolution, such as: treatments, heating, irradiation etc., this gave the possibility of obtaining Synthetic Gems retracted further to create internal inclusions similar to those of Natural Gems,  with the aim of getting as close as possible to the aesthetic aspect of Natural gems.

As you can imagine, the more the Natural Gem has value and demand on the market, the greater will be its Imitations, it is surely the case of the Diamonds considered the King among the precious gems. As already mentioned, the main Imitations of the known Diamonds are: Lead glass, GGG, Lithium Niobate, Strontium TiTanate (Fabulite, Diagem), YAG, Cubic Zirconia ( Dievalite, Phianite, Fianite) commonly ( erroneously) called Zircon , Synthetic Moissanite, Synthetic Diamond.

 In most cases you are talking about artificial gems whose appearance imitates diamonds, but hardly equal or equal in splendor and beauty, while in other cases, you can get as close as possible, like with synthetic Moissanite and synthetic diamonds , having now reached excellent levels.

Let's talk about the 2 most used and widespread Artificial stones in the jewelery and Bijoux , Strass and cubic Zirconia.

Cubic Zirconia ("Zircon"): This Artificial stone is certainly the best ever among the "poor" imitations of Diamonds, the cubic Zirconia , widespread on the market today, is erroneously called Zircon , this terminology is now widespread and affirmed, being normally used by everyone, including employees of the sector.

Especially the Gemmologists (but not only), try to maintain the correct terminology, as there really is a Natural Gem with the name Zircon , which has nothing to do with loose cubic zirconia, a different Chemical, Crystalline and Hardness structure.

Strass: It is an artificial product created by man, a lead glass, those that many would define as a simple crystal with a high lead content to increase brightness and "resistance", a simple cut is applied to this crystal as standard with some veneers, and the lower part (pavilion) is covered with materials to increase the brightness.

Rather than being a simple ornamental stone, zircon is also of scientific interest as this stone is totally different from the others and makes it an exceptional stone.

From zarqun or Zargun, zircon, sometimes confused with its almost homonymous zirconium, is what could be called a "colored gem", a colored crystal, sometimes green sometimes dark red, yellow or orange yellow or brown.

Among the oldest stones that exist, cubic zirconia stones are rare because of the complexity of its formation that merges with the formation of the Earth itself. Indeed, zircon is usually formed during the formation of plutonic rocks, such as granitoids which are mostly at the base of the formation of the earth's crust. Zircon is therefore as old as the Earth itself.

Zircon has long been known to men who have incorporated it into their myths, donning this stone with a divine aura and endowing it with magical powers. Thus, the Hindu poets speak of the Kalpa tree, covered with golden fruits and zircon leaves, given as an offering to the gods of the Hindu pantheon, while in the Middle Ages it was given the faculty of soothing sleep and to bring prosperity and wisdom.

With its supposed powers, zircon has exerted a great fascination on all civilizations, as evidenced by the enthusiasm of collectors to collect all the nuances of this stone. However, transparent zircons are the most used in jewelery, because of their resemblance to diamond, which makes this stone an ideal substitute to adorn the most beautiful works of jewelers. Apart from believing that wearing zircon is easy. This stone, being one of the heaviest stones that exist, and can also be easily scratched, requires the attention of its owner at all times, at risk of damaging a possible masterpiece.

Cubic zirconia price ranges from $10- $1000. Its average price is about $100 for very good quality stones.

The colors of the emeralds vary from a yellow-green to a deep blue-green. These are the darkest stones that we call "emeralds", the others are green beryls. For millennia, emeralds are considered sacred. In ancient Egypt, Cleopatra equated them with magic. In Latin America, the Incas and Aztecs dug in the earth to extract these divine stones from 500 BC. The Colombian territories filled with emeralds and gold are at the origin of the famous legend of El Dorado. These stories of treasures by thousands animated many Europeans who then began to conquer the El Dorado, it was the beginning of colonization and conquistadors. The Spaniards have loaded the emerald boats to Europe to exchange them for gold in Egypt, India and Persia.

Colombia has 150 emerald deposits, the main ones being Muzo, Coscuez and Pita. They form the belt of emeralds in the Eastern Cordillera of the Andes and its high steep mountains covered with a dense jungle, in the regions of Cundinamarca (Bogota) and Boyaca (Villa de Leyva / Tunja). Emeralds are mined in narrow tunnel or open pit mines.

A mineral from the group of silicates, subgroup of cyclosilicates, emerald is the most prestigious member of the family of beryl. Its famous green color, very stable in light, varies from pale green to deep green. It is most often due to chromium which enters into its composition or sometimes to vanadium (these are the rare vanadiferous emeralds).

Its hardness is 7.5 / 8 on a scale of 10. Transparent to translucent, the emerald often has inclusions of crystals, sometimes carbon that draws a star pattern (asterism). Liquid or gas may disturb it more or less. The emergence of emeralds results from the action of magmatic or hydrothermal veins on metamorphic rocks (transformed as a result of pressure or elevation of temperature). They are found under various appearances in quartz, micaschists, and pegmatites. Emeralds are frequently associated in deposits with albites, apatites, aragonites, barytes, calcites, dolomites, fluorites and pyrites.

The emerald remains one of four stones designated "precious" with diamond, ruby and sapphire, even though this name no longer officially exists since 2002. It is usually cut into a canted rectangle, this traditional form facets will take the name of "emerald cut".

Difference between natural sapphires and laboratory created: Sapphires are created naturally and also created in labs. The main difference between a natural and a laboratory sapphire created is its origin.  Laboratory created sapphire has the same physical properties, visual characteristics and level of hardness as natural stones. Natural sapphires are created by the earth and exploited, which makes them rare. The created lab stones are created by humans in a carefully controlled and common environment.

Here in Chanthaburi, Thailand, a local gemological laboratory university is exploiting the rights to the gemstone market. With gemologists trained at the famous Asian Institute of Gemological Sciences (AIGS) in Bangkok, they can test gems in a few hours so that offers can be closed quickly.

Currently many well-equipped laboratories are doing basic gem identification tests quickly and inexpensively. But the jewelery treatment test can take longer and have higher costs.

An issue for gemstone testing companies is how to maintain consistency between labs and in the way gemstones are described. If a laboratory describes a stone as "Tourmaline elbait copper" and another laboratory describes the same stone as a "Tourmaline Paraiba", the certificate indicating "Paraiba Tourmaline" may very well give the owner of this stone an advantage in the market.

To this end, some of the most respected gemological laboratories in the world have created an organization called Laboratories Harmonization Committee (LMHC), whose purpose is to standardize the formulation of reports as well as certain methods of analysis and results interpretation.

Magnificent Swiss blue topaz entirely faceted with a very good quality. The stone is natural and despite its name does not come from Switzerland. However, the name Swiss Blue Topaz or commonly called Blue Swiss Topaz is a stone that has undergone several treatments.

In fact, the first treatment is the irradiation of the stone which makes it possible to transform the natural color of an often clear stone by another color. The second treatment is the heating of the stone which makes it possible to accentuate the color obtained by the irradiation. These methods are always used when you buy a natural Swiss blue topaz with this particular name no matter where you buy it.

Topaz are found in several parts of the world: Sri Lanka, Madagascar, Myanmar, USA, Pakistan, Brazil, Russia, China, Nigeria and other countries whose production is lower. The most important deposit is located in the state of Minas Gerais in Brazil where we find topazes of all colors including the imperial topaz (orange-red) which is exclusively extracted from two mines in this region. Natural pink topaz is extracted in North Pakistan and Russia. Finally, the very pale or pale blue topaz used to obtain the blue topaz (and in particular the beautiful Swiss blue topaz) is extracted from Brazil, Sri Lanka, China and Nigeria.

Topaz exists in almost all colors: white, blue, green, yellow, orange, red, pink, purple and even multicolored. The most famous and common are the topaz London blue; we find very light pastel blue to the "Swiss blue", a beautiful intense and vibrant blue sky. It is magnesium, titanium and iron that are at the origin of the colors yellow, brown and blue. The chrome element is causes the colors pink, red and purple. Topaz is a pleochroic gem, which means that its shades vary according to the angle of vision and thus gives a lot of glare and shine to the stone. Some Topazes may become bland when exposed to intense light radiation, so avoid exposing these gems to direct sunlight.

White zircon is a natural mineral, so it is imperfect and has more or less visible inclusions. These inclusions are natural features, and allow verifying the authenticity and origin of the stone. In a stone of good quality, the inclusions are tiny, and it is only with a microscope x10 that we can distinguish them. The purity of wholesale loose gemstones will be determined by the quantity and arrangement of its inclusions. Most good topaz does not have inclusions visible to the naked eye.

There are thermal treatments for magnifying topaz that are perfectly accepted by the major recognized laboratories of expertise. The colorless or very light blue stones, present in large quantities in Brazil, are very often heated to 300C ° in order to obtain gems of an intense blue: the sublime topazes of Swiss blue color. This treatment is durable over time and does not alter the stone. Some topazes may lose their color saturation in daylight. The original color can be restored by X-ray radiation.

Amethyst is the most popular stone of the quartz family. His name in Greek means "without drunkenness" because the water that was poured into amethyst cups took on the color of the wine. Amethyst is also considered a traditional stone among bishops and other religious figures. It is said to contribute to the proper functioning of the nervous system and to prevent insomnia.

Despite its prevalence, amethyst has been one of the world’s most revered stones for many centuries. This stone is found in Brazil, Mexico, Africa, Canada and Europe. Their belief was that the amethyst crystal meaning was the same with luxury. As such, it was highlighted as part of their crowns, scepters and rings. Christian bishops once wore green amethyst stone jewelry in the form of a ring. Its color was meant to symbolize royalty and an allegiance to Christ. Members of the Catholic clergy wore amethyst stone in their crosses because for them amethyst meaning was one of holiness and celibacy. It is even thought that the breast plate of the high priest of Israel was adorned with an amethyst as its ninth stone. It’s said that there were ten stones upon which the names of the tribes of Israel were engraved, and amethyst is believed to have been one of such stones. Amethyst healing properties are as bountiful as the stone itself.

Blue Sapphire: Sapphires are made of corundum, also known as aluminum oxide. The heat used to make the stone comes from the ground and they are extracted from the ground. Natural stones are valued for their rarity and the fact that no two are alike, making each one unique. Natural sapphires have natural inclusions (flaws) in them, and present a distinctive color based on the region where they are produced from. Because of the mystery and romance associated with owning a natural stone, many choose a natural sapphire simply.

Better known in its blue color, Sapphire can take many colors. It is often associated with fidelity, and it is fashionable to offer an engagement ring, Lady Diana is not mistaken. Synthetic blue sapphire is also a symbol of purity, wisdom and immortality. It is the stone of the Balances.

Hydrothermal emerald stone is a synthetic stone (made by man through the hydrothermal process). Hydrothermal emerald stone has the same physical, chemical and optical properties. Only an expert eye or a laboratory can recognize that it is a synthetic stone.

Created laboratory sapphires are made using corundum just like natural stone is. However, they are created in a laboratory and grown under carefully controlled conditions and simulating the high pressure and heat of the earth to reproduce a natural sapphire. The heat used to create them comes from a machine and produced either by flame fusion or a molten flux method. Lab made sapphire do not scratch or chip more easily than natural stones, and are appreciated for their AAA pure quality rating.
