Loose Pink Diamonds
Investing in pink diamonds sits in a narrow range of alternative investments that work well as a portfolio asset. The supply story is structural, white diamond pricing and pink diamond pricing follow different drivers, and the closure of the major Western Australian source in 2020 has effectively ended the supply of new investment diamond material from that region. For investors evaluating coloured diamonds, other coloured gemstones or gold as a portfolio addition, the pink category sits among the more interesting truly unique investments available to Australians today.
At our Mt Hawthorn studio in Perth, we hold one of the larger inventories of investment-grade Australian pink diamond stock in Western Australia. We provide expert advice on pink diamond investment to clients across Australia, including Western Australia AU, Victoria AU, New South Wales AU, Queensland AU, South Australia AU, Tasmania AU, Northern Territory NT and Australian Capital Territory AU. The first consultation is private and carries no obligation.
Why The Investment In Pink Diamonds
Pink diamond investment rests on three structural foundations.
The first is finite supply. Around 90 per cent of the world’s pink diamonds sourced from a single Western Australian mine in the East Kimberley region until that operation ceased production in November 2020. The mine, operated as a family-led group within a major mining house, supplied the bulk of Australian pink diamond inventory traded in the secondary market today. With production ended, no new stones enter supply.
The second is consistent demand. The Australian pink diamond trade has buyers across Japan, China, South Africa, the United States, Europe and the Middle East. Australian Diamond Analytics, the leading index tracking pink diamond pricing benchmarks, has recorded strong appreciation across most measurement windows from 2005 onward. Diamond brokers report consistent buyer entry into the market each year through dealers, auction houses and direct studio purchases.
The third is the compound annual growth rate. Industry estimates place CAGR on investment-grade Australian pink diamonds in the 8 to 15 per cent range across the past two decades, with higher intensity grades (Fancy Intense Pink and above) generally outperforming Fancy Light material. During periods of economic uncertainty across 2020 to 2024, pink diamonds held value where some traditional assets faltered, which is part of why investors looking for low correlation with stocks have moved into the category.
We are jewellers rather than financial advisers, so the conversation focuses on what we can verify (the stone, the GIA certificate, recent comparable sales, current market trends) rather than forward-looking projections. Specialist financial advice is recommended for any major investment portfolio decision.
Origins And Supply: A Brief History
Pink diamonds have been recovered from only a few regions across recorded history. The Golconda region of India produced famous pink stones across the seventeenth and eighteenth centuries. The Minas Gerais region of Brazil yielded occasional pinks across the same period. South African and Russian mines have contributed smaller volumes more recently.
The dominant modern source was the Western Australian mine in the East Kimberley region, roughly 3,000 kilometres north of Perth. That single operation produced approximately 90 per cent of global pink diamond supply across its working life. The annual tender released a small parcel of the mine’s finest pink stones to specialist buyers through closed-bid competitive bidding, with prices set by international diamond brokers. The figures established at those tenders set the international pricing benchmark for the category, and the documentation issued by the mine became the standard for verified Australian-origin stock.
The mine ceased production in November 2020 at the same location it had operated from for decades. What remains is the finite stock of stones already mined, cut and certified before the closure. These certified pink diamonds trade today through specialist dealers, private collectors, SMSF trustees and a small number of investment funds. Each transaction reduces the available stock further, and the supply does not refresh.
Understanding Pink Diamond Grading
Pink diamonds are graded on a different scale from white diamonds. Where colourless diamonds use the GIA D-Z colour scale, pink diamonds are graded across three attributes: hue, tone and colour intensity.
The intensity grades for pink diamonds, established by both the Gemological Institute of America and major Australian valuation bodies, run through:
- Fancy Light Pink: soft, low-saturation pink, entry-level investment category.
- Fancy Pink: mid-range saturation, often paired with secondary modifiers.
- Fancy Intense Pink: strong saturation, where the investment-grade conversation typically begins.
- Fancy Vivid Pink: top-tier saturation, the grade collectors target, commanding a substantial premium over lower intensities.
- Fancy Deep Pink: deeply saturated darker tone, commanding premiums alongside Fancy Vivid.
Secondary colour modifiers (Purplish Pink, Brownish Pink, Orangey Pink) sit alongside the primary grade and affect price. Pure pink commands premiums over modified pinks at the same intensity grade.
Australian-origin stones from the now-closed Western Australian source also carried a separate tiering system during the mine’s operational years, with serialised certificates and a laser-inscribed unique lot number on the girdle of each stone. That documentation continues to add meaningful value in the secondary market.
The world’s foremost authorities on diamond grading include both the Gemological Institute of America (GIA) in the United States and major Australian valuation bodies. Our valuations carry signatures from registered valuers holding accreditations through the National Council of Jewellery Valuers (NJVA) and the Gemmological Association of Australia.
Investment-Grade Versus Jewellery-Grade Stones
The distinction between investment-grade and jewellery-grade material matters because the buying logic differs entirely.
Investment-grade pink diamonds focus on certified provenance, top-tier intensity grades (Fancy Intense and above), pure colour without secondary modifiers, clean clarity (typically VS or higher), and full documentation including the original mine certificate where available. These stones are usually never worn. They sit in approved secure storage, accumulate value through holding, and trade at substantial premium over jewellery-grade material at the same headline carat weight.
Jewellery-grade pink diamonds are bought to be set into a piece and worn. The colour grade can run lower (Fancy Light Pink, Fancy Pink), modifiers can be more flexible, the size is usually smaller, and the price per carat sits below investment-grade material. We see strong demand for jewellery-grade pinks for engagement rings and pendants across Perth.
Many of our clients hold both: an investment-grade stone as a portfolio asset, and a separate jewellery-grade stone in a ring or pendant. The two categories serve different purposes and respond to different drivers.
How To Invest In Pink Diamonds
Investing in pink diamonds involves more thought than buying a stock on the ASX. A few practical steps:
First, decide on the budget. Entry-level investment-grade pinks start around AUD 15,000 to AUD 30,000. Mid-range positions sit in the AUD 50,000 to AUD 250,000 range. Six-figure stones with strong colour are seasoned collector territory; seven-figure stones sit in the Fancy Vivid top tier.
Second, work with a specialist rather than a generalist retailer. Stelios Jewellers has been recognised as a specialist in the pink diamond trade for almost two decades, with relationships across Australian diamond brokers and international suppliers carrying finite remaining stock. The pink diamond market is small, the authentication risks are real, and the difference between investment-grade and jewellery-grade material at the same headline grade can be substantial.
Third, ask to see the stone in person. Pink diamonds shift visibly under different lighting conditions; the saturation that reads on a photograph differs from how the stone reads in person. Perth clients can visit the studio; interstate clients can arrange video viewings or supervised stone delivery for inspection.
Fourth, plan for the long hold. Pink diamond investment is illiquid by nature. Most investors hold for ten years or more to realise meaningful appreciation. Short-term flips rarely work because of transaction costs and market timing risk. Risk tolerance varies; novice investor entries should start at smaller allocations and grow into the category gradually.
The final choice between specific stones in a comparable range usually comes down to colour preference, modifier preference and personal investment goals. We are happy to lay out three or four candidate stones with similar specifications so you can pick just the right ones for your portfolio.
What Clients Say About The Process
Client feedback from previous pink diamond commissions at the studio centres on three themes consistently. Communication demonstrated through each stage of the purchase has been described as immensely helpful, particularly for first-time investors navigating the certification, provenance and storage decisions. Personal investment briefs are met without the high-pressure sales tactics common in other parts of the diamond industry. And clients who have come in with specific colour requirements (a particular shade of pink, a specific modifier) have left with the right stone rather than the closest stone available.
Across the past two decades we have placed literally hundreds of pink diamonds with Perth and interstate clients, including milestone pieces, SMSF holdings, syndicate investments and one-off collector commissions.
SMSF Holdings, Storage And Insurance
Self-Managed Super Funds can hold pink diamonds as investment assets under specific compliance rules established by ASIC and superannuation legislation. The stone must be stored in an approved secure facility, never worn personally, insured separately, and held in the SMSF account as an investment.
We offer secure storage at our Mt Hawthorn facility, fully insured and approved against the requirements of ASIC and superannuation legislation. Clients can also use external specialist storage providers depending on their preferences.
Insurance for investment-grade pink diamonds requires a specialist policy that reflects current market valuation rather than the original purchase price. We provide full valuation documentation through a registered valuer that most jewellery insurers accept, with valuations left unchanged from the original certificate where appropriate or updated to current market where required. Re-valuation every two to three years is recommended to keep the policy aligned with current pricing.
Risks Worth Knowing
A balanced view acknowledges the risks alongside the upside.
Illiquidity is the first concern. Selling a pink diamond at full market value takes time and the right buyer. Auction sales involve fees of 15 to 25 per cent across buyer and seller premiums combined. Private sales can be faster but often realise lower prices.
Authentication risk applies to any high-value gemstone. Treated, synthetic and misrepresented stones exist in the market. We mitigate this risk by working only with certified material from established suppliers, but the buyer should never skip the independent GIA grading step.
Market volatility exists in pink diamonds, just on different cycles to listed markets. Major auction results can shift perceived market value within days. Storage and insurance costs reduce net returns and should factor into any investment calculation.
