Gold and diamonds have captivated humanity for centuries — but as investments, they couldn’t be more different. Here’s everything you need to know, broken down simply. 

Gold vs. Diamonds: The Core Difference 

Gold is like money. 

  • Standardised, liquid, and traded globally 
  • One ounce of gold = one ounce of gold, anywhere in the world 
  • Price is transparent and publicly available 24/7

Diamonds are like art. 

  • Every stone is unique — graded on cut, clarity, colour, and carat 
  • Pricing is subjective and often opaque 
  • Finding the right buyer takes time and expertise 

 

Liquidity: How Easily Can You Sell? 

Gold ✅ Very easy 

  • Sell at any coin dealer, pawn shop, or online platform 
  • You’ll typically receive within 2–5% of the spot price 
  • Gold ETFs offer near-instant liquidity

Diamonds ❌ Much harder 

  • Most sellers recover only 20–50% of their purchase price 
  • Retail jewellers rarely buy back at fair value 
  • Exceptional stones may sell at auction — but that takes months 

 

Historical Performance 

Gold has stood the test of time as a safe-haven asset. 

  • Rose 25% during the 2008 financial crisis
  • Hit all-time highs above SGD $2,700 per ounce during the 2020 pandemic
  • Central banks worldwide hold it as a reserve asset

Diamonds have a more complicated story. 

  • Prices were historically controlled by De Beers to maintain artificial scarcity
  • Since De Beers lost its monopoly, prices have become less predictable 
  • Rare stones (e.g. Argyle pink diamonds) have appreciated sharply — but these are the exception, not the rule 

The Lab-Grown Diamond Problem 

This is a big one for investors. 

Lab-grown diamonds are chemically identical to mined diamonds — and they now sell for 30–50% less. 

  • Major retailers sell them alongside natural stones 
  • Younger buyers increasingly prefer them for ethical reasons 
  • This puts downward pressure on natural diamond values over the long term 

Gold? There’s no lab equivalent. It cannot be synthesised economically. That scarcity is permanent. 

Storage & Ongoing Costs 

  Gold  Diamonds 
Storage cost   SGD $180–$550/year Lower physical cost, but… 
Insurance  Minimal for ETFs  1–2% of appraised value/year 
Maintenance  None  Certificates must be maintained; stones can chip 
ETF option  ✅ Yes  ❌ No equivalent 

 

The Verdict 

For most investors, gold is the clear winner. 

  • Easy to buy and sell 
  • Transparent pricing 
  • Proven hedge against inflation and market downturns 
  • No specialist knowledge required

Diamonds can work — but only if: 

  • You buy at wholesale prices 
  • You have gemological expertise or strong dealer connections 
  • You’re focusing on rare, investment-grade stones (fancy coloured diamonds, large exceptional pieces) 
  • You’re prepared to wait years for the right buyer 

Rule of thumb: Treat diamonds as a luxury purchase you happen to own. Treat gold as an investment. 

Frequently Asked Questions About What Is A Better Investment: Gold or Diamond

Gold. It’s liquid, transparently priced, and requires no specialist knowledge. Diamonds demand expertise and dealer access that most beginners simply don’t have.

Poorly, for typical consumer purchases. Most people sell diamonds at 20–50% of what they paid. Only rare, investment-grade stones — such as large fancy coloured diamonds — have shown meaningful appreciation.

Negatively. Lab-grown diamonds are chemically identical and cost 30–50% less. As consumer acceptance grows, they put sustained downward pressure on the resale value of natural diamonds. 

A common recommendation is 5–10% as a hedge against inflation and market volatility. Gold’s negative correlation with stocks during downturns makes it a useful diversifier — diamonds offer no such protection.
