Argyle Mine, East Kimberly

Genesis Rare Diamonds features stones from the world famous Argyle Mine, located in East Kimberly, which is a region of northwest Australia. Covering a 110-acre area, the Argyle Mine is the globe's leading diamond mind in terms of volume.

Established more than a quarter century ago, the Argyle Mine is best-known amongst coloured diamond sellers such as Genesis Rare Diamonds, as it's the site of the world's only substantial deposit of pink diamonds. Pink diamonds are the rarest of all coloured diamonds, followed by red diamonds, blue diamonds and yellow diamonds. It's estimated that 9 out of 10 of the world's pink diamonds come from the Argyle Mine, so it's favoured high-end natural coloured diamond buyers and sellers like Genesis Rare Diamonds.

What's more, the Argyle Mine is also a leading producer of other coloured diamonds, including blue diamonds, champagne-coloured diamonds and cognac-coloured diamonds. Cognac and champagne colours are both variations of brown.

The Argyle Mine, which exports an estimated 8 million carats per year, recently transitioned from a pit mine to an underground facility; it's expected to continue operations until 2018 or 2019, if mining engineers' predictions are correct. Approximately 760 million carats of diamonds have been mined from this location. The largest diamond was mined in 1991, weighing in at an incredible 42.6 carats.

Notably, with the fast-approaching closure of this mine, pink diamonds are expected to become even more scarce. Since 90 to 95% of the world's pink diamonds are sourced from the Argyle Mine, virtually no new pink diamonds will enter the world's markets. So now is an ideal time to invest in natural pink diamonds, as the price and demand is certain to rise dramatically once mining operations cease by the end of the decade.

This mine is also unique in that it's the first commercial operation to successfully utilise an underground lamproite volcanic pipe, which was formed by lava flows which ultimately receded, leaving a tube encrusted with gems that were thrust toward the earth's surface from the depths of the planet's mantle. Most diamond mining operations are created around kimberlite pipes. The U.S. is home to another diamond mine that utilises a lamproite pipe, located in Arkansas.

Notably, all pink diamonds mined from the Argyle Mine in 2005 or later are laser-engraved with the Argyle Mine logo as part of the GIA certification process.

Did you know..... 

- Many diamond sellers use special lighting to make their diamonds look more attractive. For instance, blue-tinged lighting can be used to make a yellow diamond look colourless. It's essential to view diamonds in natural light in order to get an accurate feel for the true colour. This is especially important when shopping for natural coloured diamonds. 

- Diamond sellers may try to market a diamond with a wider-than-average table as a showy, “special” diamond. In reality, the diamond may look larger, but it's a trade-off, as the diamond will have a “shallower” pavilion, resulting in less brilliance, glimmer and sparkle. It will lack depth and it will take a hit in terms of cut grading. Cut is one of the 4 C's of diamond quality. 

- You should always purchase a diamond with a certificate, issued by an objective third party. This enables you to get an accurate, honest evaluation of the diamond and its value. There is little or no room for deception since GIA certificates contain a high level of detail, which makes it easier to ensure you're making a well-informed purchase. 

- Diamond certificates are especially important for natural coloured diamonds. Another coloured gemstone could be passed off as a coloured diamond to someone with an untrained eye. This makes certification extremely important, as coloured diamonds are many times more valuable than other similarly coloured gems. 

- Less-than-honest diamond sellers may sell non-certified diamonds that are already mounted in a setting. The setting can be used to conceal flaws, which can dramatically impact value. All diamonds should be certified and graded while loose. 

- Unsavoury diamond sellers may try to pass off a laboratory-made diamond as a natural one. There is a major price differential and it's difficult for the average consumer to determine the difference. This is especially true for pink diamonds, which are expected to skyrocket in value in the coming years, as the Argyle Diamond Mine – producer of 90 to 95% of the world's pink diamonds – is expected to close by the end of the decade. Genesis Rare Diamonds sells an array of pink diamonds from the Argyle Mine.

Coloured Fancy Diamonds

Diamonds come in a wide array of colors. Of course, the most valuable and highly desired diamonds are generally white diamonds, with “colorless” being the most desirable. 

But many diamonds that come in colors other than white. These colored diamonds are also called “fancy” diamonds. Take the famous Hope Diamond for instance: this massive 45.52-karat fancy diamond is a rich steel blue in color. Deep blue diamonds are extremely rare and while the Hope Diamond is not the largest diamond in existence, it is the largest dark blue diamond known to exist.

Diamonds are formed when carbon is exposed to intense pressure and heat. The presence of trace minerals can alter the diamond’s color if they interact with the carbon during the formation process. Other factors, such as radiation, can also impact color.

Diamonds come in an array of different colors, including red, orange, brown, yellow, olive, green, blue, white, grey, black, purple and pink. Colored diamonds can be created synthetically, but the natural diamonds are the most valuable due to the rarity.

Naturally-formed pink diamonds are considered the rarest among fancy diamonds. The extreme rarity means the prices are incredibly high and they’re so uncommon that many jewelers may go their entire career without ever seeing a naturally-formed pink diamond. Similarly, red diamonds are also very rare -- so rare that it’s believed they’re actually created due to imperfections in the lattice of crystals that comprise the gemstone.

Naturally-formed blue diamonds are the second runner up in terms of rarity, but the discovery of blue diamonds in new mining regions has resulted in a greater supply of blue diamonds.

Natural yellow diamonds are also quite rare, though there has been a relatively new discovery of yellow diamonds in Arkansas. It’s important to note that truly yellow diamonds, which are formed when trace levels of nitrogen are present, are desirable and valuable. Many confuse yellow diamonds with white diamonds that have a yellow tinge; these are considered to be less desirable, but they are not true yellow diamonds. They‘re white diamonds with a yellow tone.

Another factor impacting the value of colored fancy diamonds is the intensity of the color. A fainter, lighter color is considered less valuable; a deep, rich and vivid color is more valuable.

Synthetic colored diamonds are created in a laboratory from cultures. They are exposed to trace elements to create specific colorations. Radiation tends to cause green colors. Nitrogen causes yellows and browns, while boron causes shades of grey and blue.

These diamonds are created on-demand in a lab; they are not mined and therefore, they are not rare; the price is much lower as a result.

Diamond Certification

In the world of diamonds, certification is absolutely critical. A certification entails a scientific analysis of the stone. It also serves as a “proof of authenticity” of sorts and it accurately reflects information about the stone, enabling the buyer to determine its true value.

Diamond certificates are issued by third-party organizations such as the Gemological Institute of America or GIA. GIA certificates are widely regarded as the best in the industry.

Certificates typically include a diamond map as well. Diamond mapping is the process of documenting the flaws on the diamond. Inclusions are interior flaws such as cracks, bubbles or mineral deposits, whereas blemishes are exterior flaws like scratches and chips. All of these flaws are “mapped” and documented, creating a one-of-a-kind fingerprint for the gemstone.

Some diamonds are also identified via a tiny laser inscription that's engraved around the girdle.
The more detailed the certificate, the more valuable and useful it is to the consumer. Notably, GIA certifications are issued while the diamond is loose; this is considered to be more accurate since the setting can be used to hide flaws.

Diamond certificates include an array of information on the diamond, such as:
  • Laser inscription number;
  • Diamond cut shape and style;
  • Dimensions and carat weight;
  • Colour grade;
  • Clarity grade and characteristics;
  • Cut grade; and
  • Symmetry, polish and fluorescence.

Certification is important for insurance purposes as well, since it includes the diamond's grading information and a map of any and all flaws, both of which serve as proof of the stone's value. This information can also be used to identify a stone in the event that it's stolen or switched – a practice that occurs among dishonest jewelers who switch a diamond with another stone of lesser value.

In short, without a diamond certificate, you don't know what you're purchasing. You're left to take the seller's word on the diamond's quality and authenticity – not a wise decision, since the seller has a vested interest and many are deceptive in an attempt to command a higher price for their stones.

In addition, GIA certification is essential for individuals who are purchasing natural coloured diamonds. While it's virtually impossible to pass off another type of gemstone as a colourless or “white” diamond, coloured diamonds are another story entirely. To the untrained eye, there are many, many gemstones that are similar in appearance to a coloured diamond and there are unscrupulous sellers who may try to pass off a gemstone as a coloured diamond.

What's more, a GIA certificate will also provide you with assurance that you're purchasing a natural stone versus a lab-grown stone, which is less valuable since it's man-made and created on-demand.
Notably, GIA certificates are not issued for low-quality diamonds with surface cracks that have been filled in to create the appearance of a higher quality stone. Therefore, by purchasing a diamond with a GIA certificate, you can effectively avoid low-quality stones.
