Argyle pink and red diamonds are known throughout the world, not just for their beauty, but also for their rarity.

Not many people believe that their diamond engagement ring is an investment, however with Argyle diamonds this is certainly the case.

Pink diamonds have been known to increase in value 20% – 30% every year. These are stones that will be enjoyed from generation to generation as they are handed down.

While light pink diamonds are found in other countries around the world, such as Russia and Brazil, the Rio Tinto Argyle diamond mine in Western Australia is the only consistent supplier of deep pink diamonds in the world.

Argyle pink diamonds are graded into five main colour types.

  1. Purplish Pink
  2. Pink
  3. Pink Rose
  4. Pink Champagne
  5. Red

Red is considered the rarest, followed by the purplish pink, pink, pink rose and lastly the pink champagne. When talking about pinks, it is quite common not to mention the clarity, as an Argyle pink diamond’s value is much more heavily weighted in its depth of pink than its clarity. (Refer to the Pink Diamond colour chart in Gallery)
