Investing in Argyle pink diamonds: A Guide

Investing in Argyle pink diamonds: A Guide

Rare. Mesmerising. Brilliant. There’s never a shortage of words to describe the natural wonder that is a pink diamond. These precious gems have held our fascination ever since they were discovered over 40 years ago in the Kimberley region of Western Australia.

If you are interested in investing in a pink diamond, our guide can help you make an informed decision. Not only is it worth investing in a pink diamond but it can be an heirloom that will surely be appreciated from generation to generation.

The Market for Pink Diamonds

While white diamonds are more commonly known and more readily available, there is a niche market for pink diamonds. This is due to their rarity, with the Argyle Mine having exhausted its reserves of diamonds in November 2020. As a result, pink diamonds may command a heart-stopping price that is incomparable to colourless diamonds.

To understand the market for these rare pink gems, it must be said that less than 1% of the 20 million carats harvested from the Argyle Diamond Mine are pink. Adding to their rarity is its inimitable beauty, which drives the value of the pink diamond further to the skies.

The Mineralogy of Pink Diamonds

While pink diamonds are one of the largest natural treasures, they are also the least understood. There are some theories as to how pink diamonds received their colouring, of which one remains the most popular: scientists believe that an intense physical shock - perhaps a volcanic eruption - distorted the crystal structure. This was found to be the case for more than 99% of the 90,000 pink diamonds that were examined in a study by the Gemological Institute of America.

Despite a number of theories, gemologists cannot agree about the specific circumstances that causes a pink diamond to develop its signature colour.

What does it mean to invest in pink diamonds?

Are pink diamonds a good investment? There is no doubt that pink diamonds are a tangible investment. The closure of the Australian Argyle Diamond Mine in November 2020 forecast to dramatically increase the price of pink diamonds. Now, there’s an eruption of interest from collectors and investors who wish to own some of the remaining Argyle pink diamonds in circulation.

If you value qualities such as beauty, rarity and eternity, then an investment in pink diamonds is a wise choice.

What to look for in a pink diamond?

Not all pink diamonds are created equal. There are a few important attributes to consider when investing in a pink diamond, of which colour and grading are of utmost significance. Here, we will discuss these diamond attributes in greater detail below.

Read our informative guide on what to look out for

Colour

When it comes to the value of pink diamonds, ‘C’ for colour will far outweigh Clarity, Cut and Carat Weight (the 3 C’s). The colour of a pink diamond is determined by the following:

  • Hue: The hue refers to the dominant colour tint of the diamond.
  • Tone: The tone refers to the amount of lightness or darkness that appears in the diamond.
  • Saturation: The saturation refers to the strength or purity of the pink that is found in the hue.

GIA Grading

The Gemological Institute of America (GIA) grades pink diamonds using both colour and clarity. The colours range from lightest to darkest by the following: Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense or Fancy Deep/Fancy

While not a huge deciding factor on price, it's always beneficial to have a secondary certificate, especially one with such high renown from the GIA.

Certification of a pink diamond

When you purchase a pink diamond, you want to be sure that it comes with an Argyle pink diamond certificate. Unfortunately, when anything is high-value, copies in the world will exist.

For your complete confidence, Pink Kimberley has a registered and recognised valuer/gemmologists on staff and we only deal with natural Argyle pink diamonds. This is evidenced by our certifications that accompany every purchase. This certificate declares the pink diamond’s source and authenticity, so you can rest assured that your investment is from the Argyle Diamond Mine. Included in the certificate will be the diamond’s carat weight, shape, clarity and colour, as well as its unique lot number.
