Pink Diamonds, are know throughout the world, not just for their beauty, but their rarity as well. Not many people believe that their diamond engagement ring is an investment, however with pinks this is certainly the case. Pink diamonds have been know to increase in value 20% – 30% every year. Certainly they are a stone that you will not only enjoy now, but future generations will also enjoy 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 was the only consistent supplier of deep pink diamonds in the world.
How are pinks graded?
Pinks are graded into 5 main colour types. Purplish Pink, Pink, Pink Rose, Pink Champagne, and Red. The red is considered the most rare, followed by the purplish pink, pink, pink rose and lastly the pink champagne. When talking about pinks, it is quite common to not mention the clarity, as their value is much more heavily weighted in its depth of pink than its clarity.
When purchasing a pink diamond, ensure that the stone comes properly certified by Argyle. All stones over 0.20ct should have an Argyle certificate with a registered lot number, so the origin of the stone can be traced. An Argyle certified stone is generally considered more valuable than a pink diamond from another country. 
how rare are pinks?
Anything in nature that is extremely rare, is also generally considered quite valuable. The Argyle mine’s pink production accounts for only around 0.1% of all the diamonds that are mined there. It has been said that if a giant mining truck was filled with all the diamonds that Argyle produces, then the deep pink diamonds that it finds each year, would only fill the ashtray.
When it comes to Pink diamonds there is not always a level of predictability with regards to price. You might find that the price difference between certain grades of pinks is only 20%, whereas with others the price difference may be 50%-80% different.
Another reason that pinks are always increasing in value, is that with the closure of the mine their demand has now far exceed their supply. Which basically means that more people want them, than there are stones available. I often use the analogy, that pink diamonds are like water front property. You might look at these properties (like the pinks) and think, that the prices are ridiculous. and that someone would be crazy to pay that much for them. However if you could fast forward ten years, you will wish that you could buy them at the old price. Unfortunately once the price moves up, it never comes back down again.
