The story of the pink diamond is almost as captivating as the rare gem itself. Across the breadth of 1.6 billion years, on a journey from the Earth’s centre, the most intriguing diamond in history emerges, with an exquisite beauty that is both regal and mesmerizing. The Australian pink diamond’s spectacular outback origin can be seen in this marvel that depicts every shade of the desert sunset, from a cherry blossom pink, a soft rose, an alluring violet to a dramatic red.
Pink Diamonds Colour Grading
The three attributes, which determine the colour grade of a pink diamond, are:
Just like in the white diamond world, Round brilliant shape will always sell for a premium over a traditional or modified fancy shape. This is because of their additional cutting wastage. Logically most people think that a round cut is the best option to invest in, this concept is an interesting one as ADI has found over the past 11 years that round pink diamonds up to 0.39ct will always be a fantastic investment but round pink diamonds larger than 0.50ct will generally return a lower profit margin due to the initial higher purchase price. There are also fewer buyers at the top end of the pink diamond price market.
Rare and Luxurious Investments
Pink diamonds are recognized as extremely luxurious items. The increase in rarity together with their popularity has significantly driven pink diamond prices up. Consequently, they are often utilized as additions to investment portfolios as excellent alternative investments.
All diamonds are assessed by the same four main attributes of diamond quality; Colour, Cut, Clarity, and Carat Weight. However, unlike white diamonds where the 4Cs are of the same importance, the colour of a Fancy Colour Diamond is the most significant characteristic of all.

What Causes Pink Diamond Colour
The unique colours in the stones are caused by different trace minerals within the compound elements of the diamonds. Depending on the origin of the stones, meaning where it is from, certain minerals are more present – therefore increasing the presence of specific colours in certain areas.
Unlike Yellow Diamonds where the colour is caused from large amounts of Nitrogen, Blue Diamonds where the colour is caused by Boron, Purple or Violet Diamonds where the colours are caused by increased Hydrogen, or Green Diamonds where the colour is caused by exposure to atomic radiation or radioactivity – the cause of the Pink Diamond colour actually still remains questionable. Scientific evidence has shown that Pink Diamonds contain high pressure graining which results in a compressed internal structure and that is thought to be the origin of the colour. Within the industry, this is referred to as ‘Plastic Deformation,’ which occurs during the crystal growth.
As a result of the increased pressure, it is extremely difficult to find a Pink coloured diamond with a high clarity grade. In fact, most Natural Pink Diamonds often contain pink internal graining lines or surface graining lines within the atomic structure of the stones.
Pink Diamond Jewellery
Even with the relatively high prices of pink diamonds, as a result of their exquisite colours, they are often used in various designs of colour diamond jewellery. Pink Diamond Engagement Rings, Pink Diamond Earrings, and Pink Diamond Pendants.
Natural Pink Diamonds have always been seen among the very rich and famous. Even today, many of the Hollywood stars adorn the most glamorous pieces of pink diamond jewellery. Just some of the more famous examples are Ben Affleck who presented an unbelievably gorgeous 6-carat pink diamond ring to Jennifer Lopez. Mariah Carey’s Diamond Engagement Ring contains a 10.02-carat Pink emerald-cut diamond, and Penelope Ann Miller was happy to show off her 3.00ct Pink Radiant Diamond Ring at the 2012 Academy Awards.
