Most people assume diamond pricing is based entirely on how a diamond looks.
It’s not.
Two diamonds can be visually identical, chemically identical, and graded almost identically on paper… yet have completely different prices simply because one was grown in a lab and the other was mined from the earth.
Put them side by side and most people would never be able to tell which is which.
Why that matters
A diamond’s value is influenced by far more than appearance.
Origin changes:
- Supply levels
- Market perception
- Resale expectations
- Production methods
- Pricing structures across the industry
That’s why a lab grown diamond can often cost significantly less than a mined diamond of the same size and quality.
The difference isn’t necessarily what you see. It’s the category it sits in.
What most jewellers don’t explain
A lot of jewellers position mined and lab grown diamonds very differently depending on what they stock most heavily or where their margins sit.
That can make the conversation biased before it even starts.
Some will push mined because it’s “traditional”.
Others will push lab grown because it allows bigger stones at lower prices.
Neither is automatically right.
The better option depends on what matters to you.
How we do it differently at London Diamonds
We work with both mined and lab grown diamonds, which means we can compare them honestly.
We explain:
- What actually changes visually
- What doesn’t
- Where the value sits
- Where paying more genuinely matters
- And where it doesn’t
For some people, mined diamonds are the right fit.
For others, lab grown offers far better value for the budget.
The important thing is understanding the difference properly before spending thousands.
What that means for you
- You make decisions based on facts, not sales pressure
- You can compare options properly side by side
- Your budget goes where it actually matters
- You avoid overpaying for assumptions or marketing
The takeaway
A mined and lab grown diamond can look exactly the same.
The price difference usually comes from origin, perception and market positioning, not from what you actually see on the finger.
