Popularity also increases their worth and according to experts at the Argyle Diamond Mine, for a pink gem you can pay up to 20x the price of white stone that’s the same size.
That clarifies why the rich and famous, including the Queen and Victoria Beckham wear pink diamonds.
When you start researching these fascinating stones it gets interesting.
For one thing, there’s not many gemological data of pink diamonds.
But we’re here to share what there is to know.
Why are These Pink Stones?
The grading for these pink stones resembles grading used for coloured diamonds in general, with names such as ‘Fancy vivid’, ‘Fancy deep’, ‘Faint’ and more.
The most expensive stones are those where the color is very strong.
Pink isn’t the only color you’ll see in these stones.
You can often find:
- Purple or purplish hues, depending on the strength of the hue
- Orange or orangy for weaker colors
- Brown colors, or brownish if it’s a very weak hue
These are secondary hues and will be mentioned in the stone’s documents, with the reference to pink being the second hue noted in the naming of the stone.
While you can find out where most coloured diamond stones get their hues from, such as green gems that have carbon atoms that have been displaced, it’s not so easy to explain when it comes to pink diamonds.
The reasons for the hues aren’t clear to experts, although some speculate that it could be because of deformations.
This may happen when stones move upwards to the surface of the earth and possibly it could change a diamond’s structure, affecting how it would absorb the light.
Where do They Come From?
These pink gems can be found across the globe, from South Africa to Russia and Canada & even Brazil.
But it’s in Australia where you’ll find the best of them, if you travel to the Rio Tinto’s Argyle Mine.
The mine has a main office in Perth and it also offers the services of cutting & polishing the stones.
Only through exclusive tendering can you purchase one of their stones.
To explain the rarity of pink stones, we provide this explanation:
The mine may obtain 1 000 000ct of rough diamonds through mining, but only 1ct will be suitable for the tendering process. And that’s where their value comes from!
1ct is the size you’ll find most often with pink gems and usually 40 – 50 stones make it onto the market in a year.
That isn’t much! You’ll have to pay between $100 000 and $1 Million/carat to own one of them, or even more.
The price will depend on:
- Hue intensity
- The cut
- How clear the diamond is
Fewer and fewer diamonds are coming onto the market, so buyers want to secure their stones before there are none to pick from.
Australia did open a new mine, Kimberley based, that will hopefully add more stones to the market again.
It’s an underground mine that will be open throughout 2020 if all goes to plan.
There will be all types of diamonds mined—it could be a total of 20 000 000ct—and pink diamonds will hopefully be included, even if only a small number of them.
Pink Diamonds: The Price You Have to Pay
Pink diamonds have some of the highest price tags on the gem market, especially intense and vivid stones.
For them the prices are equal to those of rare blue gems.
Even for small diamonds you’ll have to pay a considerable amount.
Price is affected by modifying hues, so you can pay a little less if you pick a stone that has brown hues apart from the pink color.
There are more of these types of stones than some other pink diamonds, so their price tags are lower.
In contrast, purple hues aren’t found often, and the rarity results in higher prices.
