The New Value of Your Gemstones Might Shock You as Mine Closures

In recent years, a growing number of gemstone mines have shut down permanently, leaving collectors and investors wondering what this means for the value of natural stones. There was a time when gemstone mines flourished, producing some of the world’s most extraordinary treasures. Today, that reality is changing.

One of the biggest reasons behind these gemstone mine closures is the depletion of resources. Many of the world’s most famous mines, such as the Argyle Diamond Mine in Australia and the Ellendale Diamond Mine, have exhausted their supply of high-quality stones. These mines were known for producing rare gems, like pink diamonds and yellow diamonds, and their closure has sent prices soaring.

Another significant factor is the increasing pressure from environmental groups and conservationists. Mining is often linked to deforestation, land degradation, and water pollution, which has led to stricter regulations in many countries. Governments are introducing tougher policies, making it difficult for companies to continue mining operations. In places like Greenland and Madagascar, gemstone mining has been heavily restricted due to environmental concerns.

Moreover, the global shift towards sustainability has changed the industry. Many consumers now prefer ethical and environmentally friendly options, reducing the demand for mined gemstones and making lab-grown alternatives more attractive. While synthetic stones may offer a more sustainable choice, they also contribute to the decline of traditional mining, further increasing the rarity of natural gemstones.

Did you know? The Argyle Diamond Mine in Australia, which closed in 2020, was responsible for over 90% of the world’s pink diamonds. Since its closure, pink diamond prices have increased by 116% in just three years.

How scarcity is driving up the value of natural gemstones

When a resource becomes scarce, its value naturally increases. This principle applies perfectly to gemstones. As more gemstone mines close, the supply of rare natural stones shrinks, making them more valuable.

Collectors and investors have always been drawn to exclusive and irreplaceable items. With mines no longer producing certain gemstones, these stones have become highly desirable in the market. Buyers are now willing to pay premium prices for gems like Paraíba tourmalines, Kashmir sapphires, and Burmese rubies, which are no longer being actively mined.

Additionally, the jewellery industry is witnessing a surge in demand for investment in rare gemstones. Traditionally, gemstones have been seen as luxury items, but with their increasing scarcity, they are now being recognised as valuable assets. Investors are looking to secure rare pieces before they become completely unavailable, much like collectors seek fine art or rare coins.

The effect of scarcity is especially evident in auctions. Recently, Sotheby’s and Christie’s have reported record-breaking prices for vintage jewellery featuring rare gemstones, indicating that scarcity has significantly impacted gemstone pricing. As fewer natural gemstones enter the market, their value is expected to continue rising in 2025 and beyond.

The impact of lab-grown gems on natural stone prices

Lab-grown gemstones are changing the landscape of the industry, and their rising popularity is affecting the value of natural stones in unexpected ways. While they provide a more sustainable and ethical alternative, they are also reshaping consumer preferences and industry trends.

One of the main reasons lab-grown gems are gaining traction is their affordability. A synthetic diamond, for example, can be 50–70% cheaper than a mined diamond. This affordability makes them appealing to consumers who want a beautiful gemstone without the high cost or ethical concerns associated with mining.

However, rather than lowering the value of natural gemstones, lab-grown alternatives are actually making mined gems more valuable. As more people opt for synthetics, the availability of genuine, mined gemstones becomes even more exclusive. This dynamic has led to an increase in gemstone scarcity pricing, especially for stones with a well-documented history and certified provenance.

Another factor is consumer perception. Many buyers still prefer the authenticity of a natural gemstone over a lab-grown one, particularly for high-end jewellery and investment purposes. The uniqueness of a natural gemstone, formed over millions of years, gives it an intrinsic value that lab-grown stones cannot replicate.

Jewellers and collectors alike are recognising that extinct gemstone mining is making natural stones even rarer. As a result, high-value gemstones in 2025 will likely continue to see a surge in demand. While lab-grown stones may dominate the mainstream jewellery market, the true luxury market remains firmly rooted in natural gemstones.

Which gemstones are becoming extinct due to mine shutdowns?

As gemstone mines close worldwide, certain rare stones are becoming nearly impossible to find. This scarcity is driving gemstone scarcity pricing to new heights, making natural gems a hot commodity for collectors and investors.

Some of the most affected gemstones include:

Pink and red diamonds from the Argyle Diamond Mine in Australia, which closed permanently in 2020.
Yellow diamonds from the Ellendale Mine, once producing 50% of the world’s fancy yellow diamonds.
Paraíba tourmalines from Brazil, are highly sought-after for their neon-blue glow but rarely found in new supply.
Burmese rubies, once abundant in Myanmar but now extremely difficult to mine due to political and environmental restrictions.
Kashmir sapphires, famous for their velvety blue hue, are no longer mined, making existing stones worth a fortune.

With extinct gemstone mining becoming more common, these stones have seen dramatic price increases. For instance, Paraíba tourmalines, which once sold for a few hundred dollars per carat, are now worth thousands due to their rarity.

How to determine if your gemstone has gained value

If you own natural gemstones, now is the time to check their worth. With high-value gemstones in 2025 fetching record-breaking prices, understanding how to assess your stones is essential.

Factors that impact gemstone value include:

Rarity – If the mine has closed permanently, your gemstone may be highly valuable.
Colour and Clarity – Unique hues or flawless stones are worth more.
Size – Larger stones generally command higher prices.
Certification – A gemstone provenance verification certificate can authenticate the stone’s origin and boost its value.
Market Trends – Check auction houses and collector demand to understand pricing shifts.

A professional gemstone appraisal from a certified gemologist is the best way to determine your stone’s market value. Investment in rare gemstones is increasing, and if your gemstone is among those no longer being mined, its price could rise further.

Where to sell your rare gemstones for the highest price

Once you confirm that your natural gemstone has appreciated in value, the next step is deciding where to sell it. Finding the right buyer ensures you sell rare gemstones profitably without underselling.

Best places to sell high-value gemstones:

Luxury Auction Houses – Sotheby’s and Christie’s are top choices for selling rare gemstones.
Private Collectors – Many collectors are willing to pay premium prices for one-of-a-kind stones.
Jewellery Boutiques – Some luxury brands purchase rare gemstones for custom jewellery.
Gemstone Fairs and Trade Shows – A great way to attract serious buyers in person.
Online Platforms – Trusted sites like 1stDibs and GemRock Auctions allow you to connect with global buyers.

Before selling, ensure your gemstone provenance is verified and that you set a competitive price based on recent auction results.

Why collectors and investors are rushing to buy natural gems

The surge in demand for investment in rare gemstones is driven by their increasing scarcity. As mines close, buyers are eager to secure genuine natural stones before they disappear entirely from the market.

Key reasons investors and collectors are drawn to natural gemstones:

Rarity Equals Value – Stones that can no longer be mined are highly sought after.
Hedge Against Inflation – Like gold, gemstones hold value over time.
Unique Characteristics – No two natural gemstones are identical, adding exclusivity.
Luxury Market Trends – High-end jewellery brands are favouring rare natural gems.

The trend shows no signs of slowing down, making now an ideal time for collectors to acquire or sell rare gemstones profitably.

Conclusion

With gemstone mine closures becoming more common, the value of natural gemstones is soaring. Rare stones like pink diamonds, Paraíba tourmalines, and Burmese rubies are becoming harder to find, making them more desirable than ever. At the same time, the rise of lab-grown gems is changing the industry, adding even more exclusivity to mined stones. Whether you’re a collector, investor, or someone who owns a valuable gemstone, now is the perfect time to assess its worth. As these natural treasures become increasingly scarce, their value will likely continue to rise.
