One of the rarest stones in the world is the pink diamond. Very few people have ever had the opportunity to even see a pink diamond in person, and even fewer have the opportunity of ever owning a pink diamond in their own diamond jewellery collection. When it comes to coloured diamonds, pink is certainly the rarest of all the colours with a fact that shows of the worlds top 66 diamonds online, one of those are pink in colour but there are several other coloured diamonds in that collection of diamonds. In the world today you will find that most of the pink coloured diamonds are mined from one area. That is the Argyle Mine located in Australia.
The fact is that only about one percent of the gemstones that are mined out of the Argyle mine are pink diamonds, which is a very small fraction in comparison to the other diamonds and gemstones that come out of that one particular mine. There are also concerns that the area has a very limited remaining amount of coloured stones. The pinkish coloured diamonds that have been mined from the area have sold in upwards of millions of dollars in auction houses around the world.
Some of the most well-known pink diamonds in existence today would be one called Darya-I-Nur. It is one of the biggest diamonds in the world. It has a rose colour to it. The exact size of the stone is uncertain because its been set in a brooch for over one hundred years. Another popular pink/rose coloured diamond is the Conde Pink which was once owned by Louis XIII. The weight of this particular pink diamond totals over 9 carats. You also have the Agra diamond which is a natural coloured light red/pink diamond that was cut down from an original weight of 32 carats but was reduced in size down to 28 carats when it was cut into a cushion shape after a sale in 1990.
The thing that many coloured diamonds have in common with each other is that they generally have a great value and hold their value longer than colourless diamonds. For the same properties involved, diamonds that have deeper, richer pink/red colours to them tend to have a higher value. When compared to similar coloured gemstones like rubies and sapphires, pink diamonds hold a great value and are more sought after by collectors and jewellery designers alike.
