While clear cut diamonds are a traditional and mainstream option for high-class jewellery, pink diamonds have quickly become the new must-have gem. While you may think that a pink diamond for sale will equal out close to or in the same range as a regular diamond, the reality is quite the opposite.

Pink diamonds are the most expensive certified jewel, with high intensity Argyle pink diamonds from Australia's mine reaching up to $1,000,000 per carat. Today we'll be exploring why pink diamonds are fetching such a high price and how this will change in the future.

Pink diamonds are rare, pink coloured gems. The second rarest form of gem available, after red diamonds, pink diamonds are a unique and precious piece of jewellery to own. While other diamonds like purple, brown, blue and green result from chemical impurity, the pink diamond’s colour source is unknown.

Within this mystery lies the basis for their increasing value and rarity worldwide. Only 40-50 carats of pink diamonds are mined within a year, with a significant 90% sourced from Western Australia's Argyle Mine. It's becoming more challenging to keep up with the rising demand worldwide.

A gemologist or jeweller will price a pink diamond by the gem's colour intensity and integral strength. Various pink diamond colour chart levels, including the following ranges, can also be translated into a numeral value from 1 to 9.

• Faint
• Very light
• Light
• Fancy light
• Fancy
• Fancy intense
• Fancy vivid, fancy dark or fancy deep

While a pure pink-hued diamond will fetch a high price, it'll be valued higher if a pink diamond has a secondary tone or colour outside of its primary hue. For example, if you've found a pink diamond with a purplish-pink shade, you'll find this will have a higher price than a pink diamond with a brown tone. Because any colour in a diamond will hide flaws, the clarity level of your pink diamond won't become as crucial when compared to colourless gems.

With the imminent closure of the Argyle Mine, which produces up to 90% of pink diamond supplies, the global distribution of pink diamonds has seen massive disturbances.

The production of pink diamonds in the Argyle mine has dropped over the last few years, with a falling rate of 80% of pink diamonds seen in 2019. With this decreasing rate, we've seen an increasing price value of 20-30% per year within Argyle pink diamond price charts.

Future projections see pink diamond price charts increasing, but by how much is unknown. Without discovering a new pink diamond mine, these prices will skyrocket as production values lower year by year.
