Are Diamonds Really Rare?

Simple, honest diamond advice from London Diamonds.

03 June 2026 4 min read

Most people grow up believing diamonds are incredibly rare.

They’re not.

There are millions of diamonds already in circulation across the global market, both mined and lab grown. New supply continues to enter the industry constantly.

The idea of extreme rarity has been heavily reinforced through decades of marketing, controlled supply and carefully managed perception.

That doesn’t mean diamonds have no value. It just means “rare” is often misunderstood.

Why that matters

  • Scarcity and value are not always the same thing
  • Supply is far larger than most people realise
  • Marketing shapes perception more than people think
  • Price is influenced by branding, demand and category positioning

A diamond can still be beautiful, meaningful and expensive without being genuinely rare.

What most jewellers don’t explain

The diamond industry has historically relied on the idea of rarity because it helps justify pricing and emotional positioning.

But most commercial diamonds are not one-of-a-kind discoveries.

Many are part of a huge global supply chain moving through cutters, dealers and wholesalers every day.

How we do it differently at London Diamonds

We focus less on artificial scarcity and more on helping you choose the right diamond properly.

That means looking at:

  • Light performance
  • Cut quality
  • Value for budget
  • Visual beauty
  • What actually matters once the ring is worn daily

We’d rather help you buy intelligently than sell you a story about rarity.

What that means for you

  • You make more informed decisions
  • Your budget goes further
  • You focus on beauty instead of marketing
  • You avoid overpaying for perception alone

The takeaway

Diamonds are not as rare as most people think.

What matters more is choosing one that looks incredible, performs properly and feels right for the person wearing it.

Questions

Frequently asked questions

Short answers to the questions people usually ask when they start looking into diamonds.

Why do diamond prices vary so much?

Pricing is affected by factors like cut quality, rarity perception, certification, origin, demand, and how the diamond is sourced through the supply chain.

Does a diamond certificate show when the diamond was bought?
  1. No. A certificate date only shows when the diamond was graded by a lab such as GIA or IGI, not when it was mined, traded, or purchased.
Can two diamonds with the same grading look different?

Yes. Two diamonds with identical certificates can still perform very differently in real light depending on cut precision, proportions, and overall make.

Are older diamonds lower quality?

Not necessarily. Some older stones can actually represent better value because pricing, demand, and market conditions change over time.

Why doesn’t London Diamonds just sell stock already in-store?

We source diamonds around your brief rather than limiting you to existing inventory. That allows us to compare more options and focus on where the real value sits.
