HISTORY OF DIAMONDS

April 6th, 2010

From myths about valleys of diamonds protected by snakes, to the production of millions of carats in rough diamonds each year, the history of diamonds is one of mystical power, beauty and commercial expertise.

Early History
The first recorded history of the diamond dates back some 3,000 years to India, where it is likely that diamonds were first valued for their ability to refract light. In those days, the diamond was used in two ways-for decorative purposes, and as a talisman to ward off evil or provide protection in battle.

The Dark Ages
The diamond was also used for some time as medical aid. One anecdote, written during the Dark Ages by St Hildegarde, relates how a diamond held in the hand while making a sign of the cross would heal wounds and cure illnesses. Diamonds were also ingested in the hope of curing sickness. During the early Middle Ages, Pope Clement unsuccessfully used this treatment in a bid to aid his recovery.

The Middle Ages
During the Middle Ages more attention was paid to the worth of diamonds, rather than the mystical powers surrounding them. Due to the heightened public awareness of the value of diamonds, mine owners perpetuated myths that diamonds were poisonous. This was to prevent the mineworkers swallowing the diamonds in an attempt to smuggle them out of the mines.

The popularity of diamonds surged during the Middle Ages, with the discovery of many large and famous stones in India, such as the Koh-I-Noor and the Blue Hope. Today India maintains the foremost diamond polishing industry in the world.

As the Indian diamond supply dwindled, smaller finds occurred in Borneo and Brazil, but these were not sufficient to meet the ever-increasing demand for diamonds. The mid-nineteenth century discovery of diamonds near the Orange River in South Africa sparked the world’s biggest diamond rush, and helped to satiate the world’s increasing appetite for diamonds.

Recent Times
During the mid-nineteenth century, diamonds were also being discovered in eastern Australia. However, it was not until late 1970′s, after seven years of earnest searching, that Australia’s alleged potential as a diamond producer was validated.

On October 2nd 1979, geologists found the Argyle pipe near Lake Argyle: the richest diamond deposit in the world. Since then, Argyle has become the world’s largest volume producer of diamonds, and alone is responsible for producing over a third of the world’s diamonds every year.

The Four C’s of diamonds

April 6th, 2010

When you are planning on purchasing a diamond it is important that you know as much as possible about how diamonds are classified. There are four topics you need to become familiar with ?Cut, Color, Clarity, and Carat Weight.
Cut

When we speak of cut we are more interested in the proportions of the diamond as opposed to its shape (Round Brilliant, Marquise, Pear, Princess, etc.) Every diamond regardless of its shape gets it brilliancy and scintillation by cutting and polishing the diamond facets to allow the maximum amount of light that enters through its top to be reflected and dispersed back through its top. A correctly cut, “well made”, stone is pictured in diagram 1. As you can see if the angles are correct the light that enters is dispersed properly back through the diamond’s top facets. When a stone is cut too shallow (diagram2) or too deep (diagram3) the light that enters through the top is allowed to escape through the diamond’s bottom and does not allow the maximum beauty of the diamond to be realized.

Color

Diamonds come naturally in every color of the rainbow. However most people are concerned with diamonds in the white range. The Gemological Institute of America (GIA) rates the body color in white diamonds from D (colorless) to Z (light yellow).

The best color for a diamond is no color at all. A totally colorless diamond allows light to pass through it easily, resulting in the light being dispersed as the color of the rainbow. Colors are graded totally colorless to light yellow. The differences from one grade to the other are very subtle and it takes a trained eye and years of experience to color grade a diamond.

Clarity

The clarity of a diamond is determined by the amount and location of flaws, or blemishes, in the diamond when viewed under 10 power (10x) magnification. GIA rates clarity grades in diamonds from Flawless to Imperfect 3 (see chart below). The Diamond Shopping Network offers you diamonds from the Imperfect 1 grade through Flawless.
Most diamonds contain very tiny birthmarks known as “inclusions.” An inclusion can interfere with the light passing through the diamond. The fewer the inclusions, the more beautiful the diamond will be.
clarity

Diamonds have the capability of producing more brilliance than any other gemstone. A diamond that is free of inclusions and surface blemishes is very rare…and therefore very valuable.

Carat-Weight

This is the weight of a diamond measured in carats. As the carat weight of a diamond increases so does its rarity and therefore its price.
One carat is divided into 100 “points,” so that a diamond of 75 points weights .75 carats. The carat-weight of a diamond is the easiest measurement to determine. Most importantly, two diamonds can be of equal carat-weight, but their value can differ greatly due to their cut, color, and clarity.

Don’t rush into your diamond purchase. Take your time and evaluate your choice carefully. It took billions (yes, billions) of years for nature to form your diamond and the skill of a master diamond cutter to bring your diamond to you. The time you spend now can bring you a lifetime of pleasure, satisfaction, and happiness.
