Choosing a diamond today is not just about sparkle, it is about values, meaning, and making an informed decision that feels right for you. One of the biggest questions modern couples ask is whether to choose a lab-grown diamond or a mined diamond.
At first glance, they look identical and that is because, scientifically, they are.
This guide explores the differences, myths, ethics and costs, so you can feel confident in choosing the diamond that truly aligns with your story.
What Are Lab-Grown Diamonds?
Lab-grown diamonds are real diamonds, created using advanced technology that replicates the same natural conditions under which diamonds form in the earth. They are not simulants (like cubic zirconia or moissanite). They are chemically, physically and optically identical to mined diamonds.
Same sparkle. Same structure. Same hardness. Different origin.
How Are Lab-Grown Diamonds Made?
There are two main methods:
HPHT (High Pressure High Temperature)
Recreates the intense heat and pressure found deep underground.
CVD (Chemical Vapour Deposition)
Builds the diamond layer by layer in a controlled chamber, producing beautifully clear stones.
Both methods create diamonds with the same durability and brilliance as mined diamonds.
Do Lab-Grown Diamonds Look Different?
No - even expert jewellers require specialist equipment to tell them apart.
Both lab-grown and mined diamonds are graded using the same standards:
-
Cut
-
Colour
-
Clarity
-
Carat
They are certified by diamond grading bodies such as IGI or GIA, just like natural diamonds.
Ethics & Sustainability
One of the biggest reasons modern couples choose lab-grown diamonds is reassurance.
Lab-Grown Diamonds Offer:
-
A more environmentally conscious alternative
-
Traceable origins
-
No traditional mining impact
-
Peace of mind
Mined diamonds can also be responsibly sourced, but lab-grown diamonds give many people confidence in the supply chain from the beginning.
Cost - What You Should Know
Lab-grown diamonds are typically:
30–60% more affordable
than mined diamonds of the same size and quality.
This allows couples to:
-
Choose a larger stone
-
Prioritise exceptional clarity and cut
-
Or simply enjoy a more accessible price point
For many, this modern accessibility feels incredibly empowering.
Durability - Do Lab Diamonds Last Forever?
Yes. They are real diamonds, ranking 10 on the Mohs scale — the hardest gemstone on earth.
This means:
-
They will not scratch easily
-
They will not fade
-
They will last for generations
Whether mined or lab-grown, diamonds are made to be forever.
Common Myths - Let’s Clear Them Up
“Lab diamonds aren’t real diamonds.”
They are. Certified, graded, and structurally identical.
“They don’t sparkle the same.”
They do. Their brilliance comes from their cut, not origin.
“They aren’t luxurious.”
Luxury today is defined by intention, ethics, craftsmanship and meaning - not just rarity.
So, Which Should You Choose?
There is no “right” answer - only the choice that feels right for you.
Choose Lab-Grown If You Want:
-
A modern, ethical choice
-
Exceptional beauty and brilliance
-
More value for your investment
Choose Mined If You Prefer:
-
A stone formed naturally over millions of years
-
Traditional romance and symbolism
Both are beautiful. Both meaningful. Both worthy of marking a love story.
