Aquamarine is a light blue gemstone that was discovered around two thousand years ago. The name of stone has its origins in the Latin language. It is a combination of “aqua” – which means “water” and “mare” with translates to “sea” in Latin. The Greeks are credited with the first use of aquamarine for jewelry around the fourth or fifth century BC. From here, aquamarine spread around the world along established trade routes. As time passed, the popularity of aquamarine increased, and peaked around the seventeenth century. When it comes to jewelry applications, the color of aquamarine has won the hearts of jewelry aficionados around the world. This is because the light blue color of the stone is quite neutral and as such, can be easily matched with all skin tones and eye colors. In fact, the color is so very mild that it is often used in jewelry and ornaments for babies and young children. Light colored stones can sometimes be heat treated to intensify their colors. In most cases, the change in color is permanent. One interesting note about aquamarine – it is found in nature in crystalline as well as in glassy or amorphous forms. The glassy form is often found in odd shapes, some with holes in them.

Jewelry designers prefer to use stones that have an intense and deep color. Stones that have tinges of yellow and brown are considered to be less valuable and less desirable compared to specimens with a pure blue color. One disadvantage of the light color of this stone is that flaws are readily apparent even to an inexperienced observer. Stones that contain flaws such as inclusions and fracture planes are not as valuable as flawless specimens. Cutting and polishing aquamarine specimens are relatively easy and therefore easy to work into a wide range of jewelry designs and patterns. Aquamarine is almost always cut with facets for jewelry applications.

Aquamarine is mined in various countries around the world. However, Brazil is undisputed leader in aquamarine production – both in terms of the quality of specimens found here as well as the volume to aquamarine supplied to markets around the world. Among the notable finds in this country are the stunning 200-lb specimen found near Marambaia, and the 50- plus pound Dom Pedro. African countries such as Nigeria, Zambia, Madagascar, and Mozambique are also important producers of aquamarine. Mozambique in particular quite often produces specimens that are said to rival the best specimens found in the Brazilian mines. On the Asian continent, India, China, Afghanistan, Pakistan and Sri Lanka have some aquamarine producing mines. However, the quality of Asian aquamarine is moderate at best, and is often only suited for costume or fashion jewelry applications. The United States of America is a relatively small producer on the world scene, even though this stone is found in several states around the country. Specimens from Massachusetts deserve special mention because the blue color of these stones is so intense that they are often compared to sapphires. One negative aspect of American specimens is that are usually small in size and difficult to process.

Some twenty years ago, calsilica started appearing in jewelry shows and gem and mineral exhibitions around the world. The specimens shown had bright and vivid colors that spanned the spectrum of the rainbow! Quite naturally, jewelry designers and fashion jewelry fans became enamored with this beautiful gemstone. Over the next several years, there was a steady increase in the demand for calsilica for jewelry designs, and soon calsilica earrings, silver pendants, rings, and other items began to appear on the market. Online and traditional jewelry stores could barely keep up with demand and the price for this stone increased steadily.

Once the initial euphoria of a new and beautiful gemstone in the world of jewelry died down, gemologists and some well-informed jewelry fans started to ask questions about the origin of this stone. In most cases, these questions arose from natural curiosity, while in other cases the questions were borne from suspicions concerning the authenticity of calsilica. At first, suppliers staunchly claimed that calsilica was a natural stone that was discovered in a mine in the State of Chihuahua, Mexico. They claimed that mining of the stone continued to present day and even provided a few photographs of the mining operations. The photographic evidence was inconclusive and the doubts about the origin of calsilica persisted. Gemologists and geologists requested permission to visit the mine and visually inspect and confirm the deposits in Chihuahua. All these requests were denied on the grounds of proprietary information. Suppliers persisted with the claim that calsilica was a natural material – a natural form of microcrystalline calcite, that was found in the veins or seams of the volcanic rhyolite rock formation. The claim was that the binding agent in the stone was a mix of natural clay minerals that hardened under high pressure and temperatures, rendering the stone in the form that we now see it today. This did little to quiet rumors that calsilica was indeed a man-made material and not a naturally occurring stone as was originally claimed. In fact, new rumors of a spectacular deposit of natural calsilica in China started to spread in the world of gems and gemology. The specimens supposedly obtained from the mine in China were quite beautiful and their colors and patterns rivaled those of the specimens from the original mine in Mexico.

To quell these rumors and answer the many questions surrounding this gemstone the Swiss Gemological Institute (SSEF) undertook a laboratory investigation of calsilica in 2002, and published their findings in one of their newsletters in 2003. To begin their investigation, SSEF purchased two calsilica specimens at a gem and mineral show in France in 2002. The seller of course claimed that the stones were natural and even produced photographs of the mine in Mexico. To further bolster their claim, they even had a letter of authentication from a laboratory in the United States stating that the stones were not man-made. SSEF performed microscopic examinations and laboratory tests on the specimens, and found that the base materials were indeed a natural form of calcite. They also discovered however, that the colored streaks in the stone contained man-made coloring pigments. They also found that the binding agent was a transparent soft, plastic-like material very similar to paraffin wax, and not natural clay minerals as was originally claimed. This investigation proved once and for all that calsilica is a man-made stone.

Agates are primarily composed of silica or silicon dioxide, the same material that makes up sand that occurs across the globe. Silica is known to be the single most abundant mineral on the planet, and since agates are mostly silica, it stands to reason that these stones can be found on all five continents and on dozens of countries. Millions of years ago, water flowing on the surface of the earth and through crevices in rocks dissolved silica. This solution then collected in cavities within the rock formation. As the water evaporated away, salt deposits were left behind. The salts were deposited in layers of varying thickness, each layer containing secondary minerals or impurities (besides by primary mineral – silica) which influenced the color of the layer. The presence of chromium in the solution caused the layer to be green in color. Copper salts on the other hand gave the layer a blue color, and iron compounds resulted in colors ranging from burnt orange to brown. In geologic time (millions to tens of millions of years) and under intense heat and pressure, the salts became petrified and formed stones as we see them today. Although agates were formed at multiple locations under a wide variety of conditions, the common factors that were required to develop agates were a source of silica-rich volcanic ash, groundwater or surface runoff that could dissolve the silica, and secondary minerals that were responsible for the colored layers of the stone.

Agates are often used in fashion jewelry where the goal is to create pieces that are beautiful and trendy and yet affordable. The demand for agates can generally be attributed to two primary reasons, both of which relate to the abundance with which this stone occurs in nature. Firstly, because of the way in which these stones formed over a wide range of conditions, the patterns and colors that occur in nature are virtually limitless. So there is always a fairly steady supply of agates in a variety of colors and patterns to suite virtually any jewelry application. Secondly, since agates are found in great abundance, they are relatively inexpensive, which makes them ideally suited for fashion jewelry.

In the world of fashion jewelry, there are a few varieties of agates that deserve special mention. At the top of that list are Botswana agates. These stones are known for their bright colors and interesting banded patterns. Botswana agates are usually cut in cabochon form, polished to a high sheen and set in sterling silver settings to make some truly stunning silver pendants. A noteworthy variety of agates are fire agates. These stones can range in color from bright flaming orange to a more subdued brownish orange. The colors are due to the iron content of the stone. Fire agates are found predominantly in Mexico, although some minor finds have been identified in parts of Central America as well. Cyclops agates have an interesting natural pattern. These agates are formed by deposition of alternate layers of black (or nearly black) and off white to white silica. The stones are cut to expose concentric circles that resemble a single eye; hence the name. Finally, petrified wood deserves mention as being one of the more unusual forms of agates.

As the stone was being formed millions of years ago, the silica solution entrapped materials like wood, leaves and other organic matter. With time, this organic matter decomposed and was replaced by minerals of different colors. Today, petrified wood has the visual appearance of the organic matter, but has the physical characteristics of rock. Cut and polished properly, petrified wood can be used to make interesting beads for fashion jewelry.

Pearls are believed to be as one of the most eye-catching and ideal gems available for purchase. These naturally formed pearls are generally presented as presents for the beloved in a man’s living, and additionally represent an ageless and ever lasting splendor.

Though pearls are naturally created ( this takes place each time a foreign thing enters an oyster, perhaps a grain of salt, and also over time this materials turns into crystallised many different layers, developing a pearl), they could even be cultivated in special farms, that use possibly fresh water as well as salt water, depending on the pearls they’re developing.

Pearls which develop from saltwater, would be the South Sea Pearls, Tahitian Pearls as well as the Akoya Pearls, and are typically far more expensive than freshwater pearls.

tahitian pearls themselves are incredibly preferred, and this is normally for their size, in the variety of 10mm, up to 20mm across. The size of a pearl generally depicts how much the pearl may be worth, and thus, these pearls can be expensive to purchase due to their demand. With that in mind, size on its own doesn’t exclusively depict a pearl’s price, the color and also appeal, together with total shape (whether it is the perfect sphere shape or perhaps not) will impact the cost also.

These pearls may be normally found amongst the atolls of the french Polynesia sections, within Pinctada Margaitifera oysters. Despite the fact that pearls are often recognised one on color, Tahitian pearls may be found in numerous colours, including black, greyish, cream, silver and many more.

Once a particular pearl and color has become picked out, you can choose which certain jewelry you wish the pearl to generally be a part of. For example, you could make your own distinctive set of black pearl earrings from your pearls that you choose. Any size of pearls can be used as earrings, and they will be into the preference of the purchaser, which are then inset into possibly silver or gold jewelry.

Bridesmaids additionally enjoy pearl nuggets being offered to them, as part of their outfit for the big day. Fortunately, ready to use pearl jewelry can be found fairly cheaply if you shop around and do not assume something too big with regards to the dimensions of the pearl or the lustre.

The scramble for gold in the late 1800s was the key to many miners and prospectors striking it rich. The Northern regions of Canada proved massively fruitful, not just for gold, but also for oil, and more recently from diamonds. While the first ground was broken in the search for diamonds in the 1960s, it would be thirty years before these mines bore a significant amount of the precious stones. Diamond-rich ore was found in the Northwest Territories in the 1990s, and since then, Canada is known for its proliferation of the stones, third on the list dominated by Botswana and Russia. The source of 15% of the diamonds on the market, Canada’s diamond supply unearthed in the last thirteen years is valued at almost $3 billion. That breaks down to about $1.5 million worth of diamonds per day! Naturally, those who have persevered through the mining process since the 60s have been rewarded mightily for their work.

Canada’s first diamond mines were located on Point Lake, near Yellowknife. When diamonds began to turn up, several more mines were built. These mines are wide, exposed pits, and the freezing temperatures can make it an incredible challenge to maintain operations throughout the year. These mines have an average lifespan of twenty years. The Canadian diamond trade is known for its exquisite finished products.

Canada’s industry also bears the distinction of being morally superior to the African diamond trade, which has been rocked by negative media attention regarding the dubious ethical practices within the business. African diamond mines are generally located in volatile nations, and the heads of the mining industry are often tied up in the funding of terrorist activity and illegal arms deals. You can identify a Canadian diamond by any number of tiny logos embossed on the underside of the stone, invisible to the eye, but identifiable when the light filters through the stone.

Canadian diamonds tend to be naturally bright white, a desirable fashion characteristic. Employees of Canadian diamond mines generally make more than a sustainable income, often earning an annual salary in excess of $60,000. There is higher security in diamond mining jobs, although there are many temporary positions to be had. The Canadian diamond trade is a major employer of native peoples, for instance, the Yellowknife Dene Tribe owns and operates a large diamond cutting and processing center. Of course, there are plenty of diamond cutting and polishing specialists who emigrate from Asia and the Middle East, and make a good living on this highly specialized skill.

Often the raw stones are shipped to Canada’s major cities: Vancouver, Quebec, Toronto, Winnipeg, Toronto, and Montreal, where they are processed, cut, polished, and mounted. The diamond industry is the source of thousands of jobs throughout Canada, both directly and incidentally tied to the trade. As the mines began to prove lucrative, it became necessary to build roads and homes in nearby areas. Business owners like grocers and restaurateurs have also benefited from the diamond industry’s success. The mines are still producing and they continue to grow.

* TRILLION

The idea of carat was actually based on the past since they used carob seeds upon weighing scales to ascertain weights. These types of seeds were similar to the diamond designs and so the word as altered as to what we now know. Additionally, many diamonds that are actually formed the natural way in destinations which have a higher pressure and temperature. It’s been recently found out that diamonds move on the top of the earth as volcanic eruptions take place. Interestingly, as technology have cultivated so we have learned how diamonds are created, professionals are actually able to duplicate the high pressure and heated up atmosphere to make synthetic diamonds.

The gemstone emerald is a variety of the mineral beryl and its deep, intense, clear green colour comes from trace amounts of chromium and sometimes vanadium.

The name emerald comes from the Greek ‘smaragdos’ via the Old French ‘esmeralde’ and like all colored gemstones, it is graded using four basic parameters, color, cut, clarity and crystal, which is synonymous with transparency, or diaphaneity as gemologists call it.

It has always been a rare and precious stone and one of the largest and most famous are the Gachala Emerald, an uncut 5-centimetre emerald crystal weighing 172 grams, found in Colombia and now in the Smithsonian Institution in New York.

A second is the Mogul Mughal Emerald, weighing 217.80 carats and dated 1107 A.H., with its obverse side engraved with Shia invocations in elegant naskh script and its reverse carved all over with poppies and foliage. The Aztecs and Incas of South America regarded the emerald as a holy gemstone.

The sultans of Turkey also loved emeralds. In the Topkapi Palace, Istanbul, there are exhibits with items of jewellery, writing-implements and daggers, all embellished with emeralds and other gems.

In early history emerald was mined by the Egyptians and in India and Austria, like anything that is scarce it became highly valued by royalty. In India it was a particularly popular stone with the rulers of the Mughal Empire. It was in Colombia where the finest gemstones were found and this remains so today.

A fine emerald must possess not only a pure verdant green hue but also a high degree of transparency to be considered a top gem. Most emeralds are oiled in order to improve their clarity, most often with Cedar oil.

If you know someone whose birthday is in or around May choose from emerald bracelets, emerald rings, or emerald earrings for the perfect gift as emerald is the traditional gemstone for the astrological signs of Taurus, some say also of Cancer and occasionally Gemini.

Green is the colour of life and of the springtime, and has also, for centuries, been the colour of beauty and of constant love. Green in ancient Rome was the colour of Venus, the goddess of beauty and love. In the ancient Indian Vedas emeralds are referred to as promising good luck and enhancing well being. Green is also the holy colour of Islam a well as being one of the highest liturgical colours in the Catholic church.

Anyone who owns a piece of jewellery containing emerald, whether it is a ring, bracelet or earrings, should be careful of their piece because although it is a hard stone it is also quite brittle.
