History of Pearls

A natural gem, pearls are shaped inside mollusks such as oysters and mussels. They are produced when an irritant such as a tiny rock or bit of sand gets within the mollusk's shell. A shiny substance, called nacre, is secreted around the thing to protect the soft interior surface of the mollusk. As layer upon outside layer of nacre coats the nuisance, a pearl is created. Glow that is reflected starting these overlapping layers produces a quality iridescent luster. This method of building a solid pearl can obtain up to seven or eight years.

The most precious pearls are completely symmetrical, relatively large and naturally formed. They contain a shimmering iridescence which is called orient shine.

How diamonds are older?

A cut diamond with a huge violet-red garnet inclusion.

Diamonds are approved to the surface of the earth by magma, or molten rock, which solidifies while it draws closer to the surface. However, the diamonds themselves is much older than the rock that they are found in.

Measuring age
It isn't at all times possible to find out the age of a diamond by examining it directly. A better process is to look at tiny inclusions, which are crystals complete from other minerals that are frequently found within diamonds. These provide out a slight radioactive indication that scientists can measure to discover how old they are.
This resources flawless diamonds, that don't have some inclusions, are very difficult to date.

A garnet inside a diamond
The diamond during the image above contains a violet-red garnet. The crimson gives us a clue to the situation and rock types that the diamond produced in, as scientists know the temperature and pressure is also needed for garnet to turn into its crystal form.
Extra minerals turn into crystals at different temperatures and different pressures.

Finding Exact information
There is some argue about how accurate the evidence from inclusions is. Various inclusions are very old and so the diamonds they are establish might also have formed a very long time ago. However, some scientists imagine diamonds could have formed around the inclusions more recently.

Synthetic diamonds
Advances within technology mean that we can now generate synthetic diamonds and contain increased our understanding of diamonds in the natural world.
Through working out the conditions needed to create synthetic diamonds, we have also learned more regarding how and where real diamonds form, and where else we might hunt for them.

Gold - How its made

The main characteristics of diamonds

Carat is a unit of quantity for the weight of a diamond with one carat equal to 200 milligrams, or 0.2 grams, also known as 100 points. Since superior diamonds are harder to find than smaller ones, the price of diamonds with value to their carat cargo goes up exponentially.

The image above shows an example of the change in carat weight with modify in the diameter about diamond. But remain in mind that two diamonds of the same weight could contain different sizes. Why? If a diamond is cut too trivial (or flat) it will have a superior diameter, but shallow depth and become visible larger.

Precious opal from Louisiana is a sandstone

The reported precious opal from Louisiana is a sandstone/quartzite with precious opal cement and matrix. It has blue or purple play of color. The material could be cut into cabochons for jewelry and other items of interest. To date, most of the material has been cut into large (over 2-inches in diameter) gemstone spheres.

Nevada is known for precious opal from Virgin Valley. The first discovery of precious opal in the Virgin Valley area was in 1905 or 1906. Since then a significant quantity of the highly prized opal has been recovered. Virgin Valley opal is comparable to any in the world for its vivid play of color and in terms of the size of material available. Individual pieces weighing over 3 kilograms have been recovered from the Virgin Valley deposits. In 1993, miners found a 100-kilogram opalized log containing precious opal. The material varies in body color from deep pure black to brown to yellowish-white to white to colorless. The play of color includes all colors common to precious opal, red, blue, green, yellow, orange, etc. The opal occurs primarily as replacement of wood, or sometimes, as replacement of conifer cones. Some opal does occur as nodules filling void spaces in clay. The wood replacement is so complete, that generally the wood grain and banding are no longer visible. The exception to this would be that often the exterior wood texture is still present as a brown or black rind.
The uses of the opal can be restricted because of crazing. Crazing is the breakdown or deterioration of opal by the development of very fine cracks all over the surface that extend until they intersect. In the worst cases, the surface of the opal deteriorates into a crumbling sand-like material. Because of the crazing the opal is not well suited for use in jewelry, but displayed in water, glycerine, mineral oil or other liquids makes remarkably beautiful mineral specimens. The mineral collections of most of the better museums contain very fine pieces of Virgin Valley opal. Many museum pieces are crazed from exposure to the air.

Gemstone gets set to shine again

Long considered two counties yet to fulfill their economic potential, eastern Taiwan's Hualien and Taitung are ready to shine at the Eastern Taiwan Gems and Jades Exhibition. Hosted by the National Taitung Living Art Center from event features more than 1,000 pieces of precious stones and jewelry.

Three famed gemstones found in eastern Taiwan, hornblende (commonly known as Taiwan jade), blue chalcedony and red coral are the highlights of the fair--a joint effort between the government and industry aimed at kick-starting the island's dormant jewelry industry and generating local employment opportunities.

According to Hsieh Jing-lin, chairman of the ROC Gems and Jades Association and co-host of the exhibition, in the 1960s and 1970s, Taiwan hornblende held a 90-percent share of the global jade market. "Back then, Hualien's Fengtian Village was a mining town best known for the precious stone and the county boasted more than 1,000 gemstone factories," he said.

But toward the end of 1970, Hualien's jade industry went into steep decline as local deposits of hornblende were exhausted. "Over the years, many people believed that untapped veins of the stone could be found in the county's mountainous regions," Hsieh said.

"Exploration was never carried out because at that time, Taiwan did not possess the know-how to prospect for these deposits," he added.

A native of Taitung, Hsieh considers Taiwan's blue chalcedony--distributed over ranges in Hualien and his hometown--to be the world's most beautiful "natural" specimen of the quartz. "Unlike blues from abroad, Taiwan's stones do not need heat treatment to improve their color," he said. "They naturally possess a pure luster and clarity, which make them the darlings of Japanese collectors."

The gem dealer said the region's old mining towns, if tastefully transformed into tourist attractions, could breathe added life into eastern Taiwan's precious stone enterprises. "People would be interested in trekking along winding paths through mines where gemstones exposed can be seen," Hsieh suggested.

Properties

It is estimated that all the gold in the world, so far refined, could be placed in a single cube 60 ft. on a side. Of all the elements, gold in its pure state is undoubtedly the most beautiful. It is metallic, having a yellow color when in a mass, but when finely divided it may be black, ruby, or purple. The Purple of Cassius is a delicate test for auric gold. It is the most malleable and ductile metal; 1 oz. of gold can be beaten out to 300 ft2. It is a soft metal and is usually alloyed to give it more strength. It is a good conductor of heat and electricity, and is unaffected by air and most reagents.

Uses

It is used in coinage and is a standard for monetary systems in many countries. It is also extensively used for jewelry, decoration, dental work, and for plating. It is used for coating certain space satellites, as it is a good reflector of infrared and is inert.

Cost

Gold, like other precious metals, is measured in troy weight; when alloyed with other metals, the term carat is used to express the amount of gold present, 24 carats being pure gold. For many years the value of gold was set by the U.S. at $20.67/troy ounce; in 1934 this value was fixed by law at $35.00/troy ounce, 9/10th fine. On March 17, 1968, because of a gold crisis, a two-tiered pricing system was established whereby gold was still used to settle international accounts at the old $35.00/troy ounce price while the price of gold on the private market would be allowed to fluctuate. Since this time, the price of gold on the free market has fluctuated widely. The price of gold on the free market reached a price of $620/troy oz. in January 1980. As of January 1990, gold was priced at about $410/troy oz.

When buying a diamond?

When you're buying a diamond, consider four criteria, often referred to as "the 4C's" - cut, color, clarity and carat weight. Each factor affects the price.

Cut not only refers to the shape of the diamond, but also to the size, angle, uniformity and polish of the facets.

Color is sometimes "graded" on a scale. However, scales are not uniform: a "D" may be the best color for one scale, but not for another. Make sure you know how a particular scale and grade represents the color of the diamond you're considering.

Clarity refers to the presence or absence of internal flaws, called inclusions, that occur naturally within the stone, or to external blemishes, such as scratches or chips. A diamond can be described as "flawless" only if it has no visible surface cracks or other imperfections when viewed under 10-power magnification by a skilled diamond grader.

Carat weight may be described in decimal or fractional parts of a carat. If the weight is given in decimal parts of a carat, the figure should be accurate to the last decimal place. For example, ".30 carat" could represent a diamond that weighs between .295 - .304 carat. Some retailers describe diamond weight in fractions and use the fraction to represent a range of weights. For example, a diamond described as ½ carat could weigh between .47 - .54 carat. If diamond weight is stated as fractional parts of a carat, the retailer should disclose two things: that the weight is not exact, and the reasonable range of weight for each fraction or the weight tolerance being used.

Famed Red Diamond Returns to Natural History Museum

The “Kazanjian Red” drew thousands of visitors when it first appeared at the Museum last October. It left four months later, stopping in Carlsbad, California where it was scrutinized by gem experts at the Gemological Institute of America. Now the diamond has returned for a second engagement in the Museum’s Gem and Mineral Hall. It will be on view from April 6 to May 29, 2009.

Though there are many diamonds with a pink hue, true blood-red diamonds are the rarest of gems — only three large stones are known to exist. And of that trio, none has as fascinating and exciting history as the Kazanjian Red.

The Natural History Museum of Los Angeles County is located at 900 Exposition Boulevard. The Museum is open seven days a week, 9:30 a.m. to 5 p.m. Admission is $9 for adults, $6.50 for students and seniors; and $2 for children 5-12.
