Argyle Authenticity - Understanding Certifications for Pink Diamonds

The world of diamonds is one where beauty intersects with science, resulting in the mesmerising allure of stones such as the esteemed Argyle Pink Diamonds. To ensure the authenticity and value of these precious gems, various certifications provide peace of mind and assurance to purchasers. Our commitment to transparency and quality is why we're updating our certification information to include detailed insights into the different types of certification when comes to Argyle Pink Diamonds and we will look at them in detail for each one of them:

  1. 1. Argyle Pink Diamond™ certificate

  2. 2. GIA certificate

  3. 3. GSL Certification (Gem Studies Laboratory)

Argyle Pink Diamond™ Certificate

The Argyle Pink Diamond™ certificate is your assurance of the stone's origin from the renowned Argyle Mine in Australia. This certification guarantees that you are purchasing one of the rarest diamonds in the world, known for its unique colour spectrum and unmatched radiance. The impending closure of the Argyle Mine has made these certificates highly coveted, as they are a token of authenticity for a finite resource steeped in luxury and prestige.

Argyle Gem Identification and Authenticity Document - "The Argyle Certificate"

An Argyle gem identification and authenticity document is provided with all Argyle diamonds that weigh over 0.08 cts and these can be verified on the Argyle Diamond website for all diamonds issued from 1st January 2009.

As a further security measure, Argyle moved to laser inscribing the girdle of all polished pink diamonds from late 2004. They began with the diamonds weighing greater than 0.20 ct and then from January 2009 it was expanded to include diamonds weighing greater than 0.08 cts. The laser inscription is a unique lot number that is only visible under magnification, a mark of its unique provenance, its sustainability and its guardianship. Many Argyle diamonds also carry grading from the Gemological Institute of America (GIA), a separate and independent grade associated with each stone.

When purchasing an Argyle pink diamond, the Argyle certificate is a must. It is the only document that is trusted worldwide and can insure that your pink diamond is of Argyle origin. The secondary security measure would be the ID No. that is laser inscribed on the girdle of your pink diamond.

GIA Certification - The Global Standard

When it comes to diamond certification, the GIA stands at the forefront. Known worldwide for setting the benchmark in gemological analysis, the GIA's Coloured Diamond Grading Report is more than just an assessment; it's a seal of global standard. Here's why GIA certification carries unmatched importance:

Comprehensive Analysis

Each GIA report provides an exhaustive evaluation that includes:

  • An accurate assessment of the diamond's colour grade, colour origin, carat weight, and clarity.
  • A plotted diagram showcasing the clarity characteristics of the stone.
  • A unique serial number that is laser-inscribed into the diamond, creates an indelible link to its report and verifies its authenticity.

Industry-Driven Research and Ethics

Founded in the 1940s, the GIA has been instrumental in professionalising the jewellery trade by:

  • Introducing the four Cs grading system.
  • Promoting standards and ethical practices in the jewellery industry.
  • Conducting extensive research that supports ongoing education in geology.

Invaluable for Investment and Legacy

An Argyle Pink Diamond with a GIA certification is more than a gem—it's a piece of history. Holding GIA documentation means:

  • An assurance on the precise characteristics of your valuable Argyle Pink Diamond.
  • Confidence in your investment, given that every feature of your stone has been meticulously documented.
