Bitcoin or Diamonds? What the Crash in One and the Rise of the Other Says About Smart Money

Key Takeaways

• Natural diamonds struggled to preserve value, whereas digital assets achieved significant growth over sixteen years.
• Synthetic diamonds have eroded traditional gemstone rarity, shifting long-standing price trends and structures.
• Bitcoin’s hard supply cap and high liquidity provide transparent scarcity and seamless trading networks.
• Combining a ring with BTC allocation blends tradition’s appeal with modern wealth preservation.

Imagine exchanging a diamond ring for a Bitcoin wallet in the search for reliable stores of value. Natural diamonds, known for rarity and emotional significance, now compete with Bitcoin, a digital currency strictly capped at 21 million coins.

Over the past few decades, diamonds have been presented as inflation-proof assets, yet industry price trends tell a different story, calling into question true diamond scarcity.

This article provides a concise overview of two decades of diamond-price movements, explains the importance of Bitcoin’s fixed supply, compares long-term wealth-preservation potential, and explores whether a BTC-based proposal could secure an affirmative response faster than a classic diamond ring, an ironic twist that may surprise.

How De Beers Shaped the Modern Diamond Narrative

From its establishment in 1888, De Beers controlled roughly 80–85% of global rough diamond distribution until the early 21st century, and as of 2020, it remains the world’s second-largest producer behind Russia’s ALROSA. 

For the past 80-odd years, diamond advertising has leaned on themes of permanence, rarity and emotional security rooted in De Beers’ 1947 “A Diamond Is Forever” campaign, transforming diamonds from luxuries into essential engagement symbols. 

By pairing an indestructible stone with the promise of undying love, De Beers drove diamond-ring penetration from about 10% of brides in 1940 to over 80% by 1990. Jewelers continue to invoke diamond legacy, stressing that natural diamonds are “forever,” immune to market swings and worthy of passing down through generations.

Now, let’s see how that promise has held up in 2025.

How Diamond Prices Have Shifted Since 2008

The chart below captures the impact of events from 2008 to recent lab-grown supply shifts, giving buyers and sellers a clear view of market dynamics.

The color-coded lines below illustrate the percentage change in per-carat prices for three key size bands being the 0–0.5 ct (teal), 0.5–1 ct (blue), 1–2 ct (purple)—over the past 17 years. 

A few takeaways stand out:

• Steady erosion for small stones: The 0.5–1 ct band is down nearly 45% from 2008.
• Mid-size resilience (and a warning sign): The 1–2 ct stones held up best but are down approximately 15% since August 2024 when prices slipped below January 2008 levels.
• Volatility vs. liquidity: Tiny stones (< 0.5 ct) exhibited sharper swings in market sentiment but are down 12% from 2008.

Why Natural Diamond Prices Are Falling—Despite Their Scarcity

For generations, natural diamonds have symbolized scarcity and by extension, value. Yet the price trends tell a different story:

• Finite but dilutable: Earth’s mines can’t produce diamonds forever but discoveries and improved extraction have kept the global supply stable.
• Lab-grown competition: Synthetic stones account for roughly 40-45% of engagement-ring sales, pressuring natural pricing from below.
• Supply-chain frictions: Diamonds arrive as mixed batches of uncut stones, sometimes in shoe-box–sized lots, which dealers must sort, grade, and cut. These factors can add 10–20% to a final retail price.
• Emotional Premium: Part of a diamond’s price is the marketing-driven promise of “forever,” a narrative that outpaces its pure investment merit.

Lab-Grown Diamonds Undercut the Scarcity Premium

Golan & Co., a family-owned Israeli diamond manufacturer and exporter, reports that 45% of 2024 engagement rings feature lab-grown centers and sell loose at prices 30–50 % below mined equivalents. 

Synthetics have eroded any scarcity premium on natural stones by cutting mine-to-market markups (grading fees, consignment costs, etc.). 

Meanwhile, decades of “A Diamond Is Forever” style marketing still command a 10–20 % emotional surcharge, not backed by investment fundamentals. The result means that natural diamonds deliver flat-to-declining prices and offer virtually no genuine upside as a store of value, as indicated in the chart below.

How Bitcoin and Diamonds Differ as Stores of Value

Compared to diamonds, Bitcoin’s value is anchored more in code than tradition:

• Hard cap of 21 million coins: No central planner can “print” more BTC, ensuring a predictable and uninflatable supply.
• Invisible yet liquid: One can’t wear BTC but one can trade it round-the-clock on dozens of exchanges, moving in and out in seconds.
• Bitcoin’s resilience: Despite historical drawdowns of 70–85%, Bitcoin has rebounded and on June 27, 2025, is priced near $107,000, demonstrating both its upside potential and its cyclical risk.
• Institutional validation: Institutional interest, evidenced by Strategy’s 592,345 BTC holdings and the launch of spot Bitcoin ETFs in January 2024, has boosted credibility and contributed to BTC’s price appreciation and global adoption. 

Bitcoin’s enforced 21 million-coin ceiling is hard-coded into its protocol, making its scarcity objective and transparent with every market participant able to verify the remaining supply. 

Bitcoin’s transparency contrasts sharply with natural diamonds, whose perceived rarity has been maintained by decades of marketing and tightly controlled supply historically, firms like De Beers commanded around 80–85 percent of global rough diamond distribution.

Why Bitcoin Outperforms Diamonds Over Time

In mid-2015, $3,000 could buy a 0.5 ct natural diamond; today, that same stone is valued at around $2,640, reflecting a 12% decline in price.

By contrast, $3,000 of Bitcoin at roughly $251 in June 2015 would have bought 12 BTC. This same $3,000 is now worth around $1.28 million. This comparison, whilst basic, underscores how a physical asset can stagnate or lose real value, while a digitally capped, widely adopted asset can deliver extraordinary, if volatile, gains.

How Can You Hedge Your Engagement Ring with Bitcoin?

One practical way to balance tradition and investment is to allocate about 70–80% of the engagement budget to the ring itself, covering the setting, design, and emotional appeal, while setting aside the remaining 20–30% for Bitcoin.

As Bitcoin’s value potentially grows over time, this strategy can help reduce the overall effective cost of the ring, cushioning any decline in its resale value.

This method keeps the sentimental value of the ring intact while also offering a simple way to add a potential hedge against inflation and market changes.

Conclusion

Diamonds still dazzle, but their price history, marked by a 50% real decline and occasional short-lived spikes, suggests limited upside as an investment. Bitcoin, despite its volatility, has outperformed nearly every asset class since its inception, driven by its fixed digital scarcity and increasing institutional adoption.

A balanced approach for buyers could be to invest in a traditional diamond ring for its emotional and ceremonial value while allocating a portion of the budget to Bitcoin. This way, the ring is effectively supported by a growing digital asset that has the potential to appreciate over time.
