Still not convinced? Here are the top 7 reasons for the rarity of pink diamonds:

1. The pink diamonds’ exceptional nature leads back to a basic truth: these breath-taking gems are among the rarest stones in the Earth’s crust.

  • They are very scarce, having formed under extremely high pressures and temperatures deep within the Earth, and are only found in certain places in the world.
  • The other 10% are predominantly from Brazil, Africa, and India, with a small amount deriving from Russia and Canada.

2. The rare, alluring beauty of pink diamonds makes them very good for investment as they are preferred by most women.

  • The very high demand for the pink diamond may be linked to their passionately romantic look and vibrant beauty.
  • According to the New York Post, pink diamonds consistently rank among the world’s most desirable gemstones.
  • Moreover, the demand for these precious pink stones has risen drastically with influential icons such as Jennifer Lopez, Mariah Carey, and Anna Kournikova sporting this pink ‘stone of choice’ as engagement rings.

3. Australian pink diamonds are incredibly rare – comprising just one-tenth of 1% of the diamonds at Rio Tinto’s Argyle mine.

  • These pink diamonds occur very sparsely alongside their coloured counterparts in different mines world-wide.
  • If you gather all the pink diamonds that weigh more than one-half of a carat in one year, these gems would easily fit in the palm of your hand.
  • According to Bloomberg, this is just about a teaspoon’s worth of pink diamonds every year, with the supply expected to diminish further.

4. Pink diamonds have travelled 1.6 billion years to get through the Earth’s surface.

  • The rarity of pink diamonds may be attributed to this long journey.
  • When you examine their facets up-close, you get to appreciate the wonder of these pink gems that speak much of the history and extreme conditions they have withstood.

5. Pink diamonds possess important fragments of history. Kings and Queens owned these rare finds.

  • When the Argyle mine closes in 2020, people entrusted with its rare pink and coloured diamonds will possess important pieces of Australia’s natural history and heritage.
  • Pink diamonds have been the diamonds of kings since the 17th century. It is believed that the pink diamond that Jean Baptiste Tavernier, a famed French writer and gem merchant called ‘The Great Table’ was eventually cut into two smaller gems, called the Noor-ul-Ain and the Daria-i-Noor. These are now both a part of the Iranian Crown Jewels.
  • Perhaps the most famous pink diamond in the world belongs to Queen Elizabeth. The ‘Williamson Pink’ was given to Her Majesty for her wedding in 1947. The cut, 23.6-carat round stone later was set in a brooch.

6. Pink and red coloured diamonds are a result of atomic deformities which affect the way light is refracted through these gemstones.

  • Just 0.03% of the diamonds mined every year across the globe are pink, and an even tinier proportion of these are pinkish-red to red.

7. Pink diamonds are a geological rarity.

  • According to, diamonds with natural body colours are incredibly scarce.
  • Out of 100,000 diamonds, only a few will have one of the rare colours. The pink diamond’s hue can have any intensity between ‘very light’ and ‘vivid’.
  • To be considered a certified coloured diamond, a pink diamond’s hue must be noticeable when the diamond is in the face-up position.

A Final Note

Bottom line, the allure of natural pink diamonds has not faltered with time and even with the advent of their artificially-developed counterparts. The pink diamonds’ billion year journey from beneath the earth, coupled with the hardships of their retrieval, and the intricate processing, and polishing carried out by experienced artisans is a beautiful story in itself that speaks of unparalleled rarity and priceless value.

True connoisseurs know that you must see these pink diamonds in person to truly understand their mythic beauty. Even the best photographers cannot seem to capture the radiant light that emanates from within each pink diamond that has been magnified through world-class artisans’ hands with over 30 years of experience in cutting and polishing Australian pink diamonds.

But in the end, many agree that its real value is beyond what meets the eye. To quote LJ West, a New York diamond enthusiast and collector, “It’s not about what it looks like. It’s the rarity that gives its value.”
