Dear Investor,

Why consider diversifying your investment portfolio with pink diamonds from a mine that has now closed?

Whether you’re a first-time investor, a sophisticated investor or SMSF Trustee, buying loose pink, red or blue diamonds for investment offers unparalleled opportunities for diversifying your portfolio, including:

  • Access to the very best diamonds for investment from a now close mine in Western Australia.
  • Low levels of risk, which through the proper management, can be reduced even further.
  • Outstanding growth rates, unparalleled in financial markets.
  • Liquidity and portability across borders and generations.
  • Ethically sourced diamonds and stones that are highly sought after by investors worldwide.

Investment quality, coloured diamonds are among the most rare and valuable commodities on the planet.

All diamonds are beautiful, but unless their quality and origin are exceptional, they would not generally be considered good investments. This is why Stelios Jewellers offer only the very best loose diamonds to buy for investment in Australia.

NFCDs from mines with depleted or dwindling stocks are more highly sought after than those from mines with an abundant supply.

Stelios Jewellers currently specialise in loose red, blue and pink diamonds. Pink diamonds are regarded as rare commodities and buying them for investment is certainly worthwhile.

Pink, red and blue diamonds are rare, with less than 0.01% of all diamonds mined globally being classified as Natural Fancy Coloured Diamonds (NFCDs). This is an industry term used to describe coloured diamonds.

If NFCD’s had a rarity scale:
• An NFCD would have a rarity scale of 7/10.
• An investment grade NFCD would have a rarity scale of 9/10.

Investment grade NFCDs exhibit extremely high qualities in their Colour, Clarity, Carat and Cut, which makes them sought after by collectors and investors around the world.

One of the features of a good diamond investment in Australia is an active re-sale market to provide sellers with buyers, and both with a means to establish a fair value when the time comes to sell. Generally, the maturity of the market for NFCD’s here in Australia and around the globe is one of its most attractive selling points.


“Diamonds aren’t just a girl’s best friend…”

Natural Fancy Coloured Diamonds are tangible and uniquely multi-purpose assets unlike shares, bonds, and other financial investments.

“Since diamonds are tangible assets, they can be insured against loss or damage, especially when the diamond in question is set in jewellery, which is a great comfort to investors. Intangible assets like stock will never have this insurance option!”
Mark Kiesel, PIMCO

A diamond will continue to appreciate with no cost to the asset itself. A diamond will look the same in 1,000 years as it did on the day it was first polished, even if someone takes it out to wear every day. As such, buying loose diamonds for investment is truly worthwhile.

Investment diamonds and rare gemstones are the world’s most portable form of wealth, enabling you to carry millions of dollars in your pocket.

Natural Fancy Colour Diamonds represent an incredible concentration of wealth compared to any other asset in the world. Undoubtedly, it’s worth considering purchasing loose NFCDs to diversify your investment portfolio.

The amount of value that is packed into 1 gram of investment grade NFCD far outstrips that of any other asset. Depending on the year and date, such expensive assets as a bar of gold, a bar of platinum, or even a valuable work of art do not pack in as much value into one gram as an NFCD!

As an example, a 1 gram (5ct) fancy vivid pink diamond has been worth $10 million, while 1 gram of gold on the same day was worth only $35!

Investing in diamonds and gold


Buying loose diamonds for investment is ideal for a balanced and diversified portfolio.

Buying loose investment diamonds and gemstones is considered to be a great option for investors who want to diversify their portfolio by acquiring stable, medium to long-term assets.

Gemstones are not subjected to the same price volatility compared to other investments, such as listed shares. To maximise their true growth potential, a medium to long-term view is necessary.

Investment diamonds from AUD$50,000.
Investment gemstones from AUD$20,000.

As the name suggests, single stone investments are a single NFCD or rare gemstone. Stones are chosen based on colour rarity, meaning good characteristics in terms of hue, clarity, grade and carat weight.


“Exceptional things will always sell for exceptional prices” – Christie’s New York

Demand for rare, investment grade diamonds has continued to grow on the back of limited worldwide supply.

The principals of economics determine this to be one of the fundamentals of a good investment. Another two fundamentals are the price you buy at and the price you sell at. The most promising investment may prove to be worthless if you don’t pay careful enough attention to these two variables.

Buying diamonds for investment

Buying at retail price is acceptable for many purchases, but investment quality diamonds and gemstones isn’t one of them.

Why pay a premium for gemstones bought from a retail shop with large overheads and profit margins, potentially requiring you to hold onto your investment for twice as long to see a return?

Specialist wholesale diamond and gemstone dealers, like Stelios Jewellers, source, cut and polish rough stones specifically for investors like you. This means you can buy an investment diamond or gemstone for a more competitive price and with a personalised service.

Sell at the right price

When the time comes to liquidate your investment, you have three options:

  • Sell your stones privately
  • Sell your stones at International Diamond fairs
  • Place your stones on consignment with an experienced, specialist investment gemstone jeweller.

Option 1 may provide you with the greatest financial return on your diamond investment, but not everyone has the expertise or industry network to find the right buyer and negotiate the best price.

Options 2 and 3 will usually deliver the current wholesale market price, but the profit realised on the sale of the investment diamond or stone will largely be determined by the initial purchase price. The best way to avoid overpaying on quality gemstones, or mistakenly buying less marketable gemstones, is to get advice from a qualified, specialist investment diamond and gemstone dealer like Stelios.



  • When a WA mine closed, it took 90% of the world’s pink diamond production with it.
  • This is a commodity that has not been affected by any economic crisis.
  • Low level of risk.
  • Demand for rare investment quality gemstones has continued to grow on the back of limited worldwide supply.
  • Over the past 30 years there have been no recorded dips in the average wholesale price per carat on investment quality precious stones.
  • The most concentrated form of wealth.
  • A way to transfer wealth from country to country.


  • Global demand decreases.
  • Finding another mine.
  • Paying too much for investment.
