What Are Lab-Grown Diamonds?
Let’s clear something up right away lab-grown diamonds are lab grown diamonds. They’re not cubic zirconia or moissanite. They’re chemically, physically, and optically identical to natural diamonds but created in a lab instead of pulled from the earth.
The Rise of Lab-Grown Diamond Rings
More and more people are saying “yes” to lab-grown diamond rings and it’s not just about the price. It’s about ethics, sustainability, and innovation. Couples are becoming smarter about their choices, and the jewellery industry is finally catching up.
Why They’re Taking Over the Jewellery Market
Once considered “alternative,” lab diamonds are now mainstream. With tech improving rapidly and demand for ethical choices growing, the market for lab-grown diamonds is booming. Just check out collections like ANZ Jewels’ rings to see why.
How Lab-Grown Diamonds Are Made
The Two Main Methods
There are two main methods to grow diamonds in a lab. Both start with a diamond seed—a tiny sliver of carbon that becomes the foundation of a gem.
HPHT – High Pressure, High Temperature
This method mimics the natural process. A diamond seed is placed in carbon and subjected to extreme pressure and heat—over 1,500°C and 1.5 million PSI! The carbon melts and begins to form around the seed, crystallizing into a diamond.
CVD – Chemical Vapor Deposition
This is the more modern method. It uses a plasma reactor to break down carbon gases, like methane. The carbon then slowly deposits onto a substrate, growing layer by layer into a diamond. This process is cleaner, more controlled, and increasingly popular.
Timeline: From Seed to Sparkle
On average, it takes 6–10 weeks to grow a diamond large enough for use in jewellery. Compare that to the billions of years it takes in nature.
Are They Really “Real” Diamonds?
Yes! Lab-grown diamonds are certified by the same gemological labs (like GIA or IGI), and they’re graded the same way: cut, color, clarity, and carat. If you put one next to a mined diamond, even a jeweller might need a microscope to tell the difference.
The Science Behind the Sparkle
Molecular Structure and Physical Properties
At an atomic level, lab-grown diamonds are 100% carbon—just like mined ones. They score a perfect 10 on the Mohs hardness scale, meaning they’re just as durable and brilliant.
Lab vs Mined: Can You Spot the Difference?
To the naked eye? No. Not unless you have advanced equipment. Both sparkle the same, reflect light identically, and offer the same timeless beauty.
The Environmental Impact
Eco-Friendly or Greenwashed?
Here’s the truth: lab-grown diamonds are significantly better for the environment than traditional mining—but not perfect. Some labs use renewable energy, others don’t. So always ask your retailer about their sourcing.
Energy Use in Lab Production
CVD diamonds generally use less energy than HPHT. Leading producers are moving toward solar or wind energy to power their operations.
Water and Land Preservation
Mining devastates ecosystems, displaces communities, and pollutes water sources. Lab-grown diamonds? They use less than 10% of the water needed for mining and leave no giant holes in the earth.
Ethical Benefits of Lab-Grown Diamonds
No Blood Diamonds Here
Lab diamonds are conflict-free. You’re not funding wars or supporting corrupt regimes when you choose lab-grown.
Safe Labor Conditions
Forget dangerous mining shafts. Lab-grown production happens in clean, safe environments—often in tech labs with highly skilled workers.
The Human Cost of Mined Diamonds
Behind many natural diamonds is a dark story: child labor, exploitation, environmental destruction. Choosing lab-grown is a vote for human rights.

How Much Can You Save?

Value Over Time
Lab-grown diamonds don’t have the resale value of natural stones (yet), but they hold sentimental value, which is often what really counts.
Investment or Sentiment?
Ask yourself: Are you buying a ring to resell or to wear forever? Most people choose based on love, not investment portfolios.
Debunking Myths About Lab-Grown Diamonds
Are They Fake?
Absolutely not. Lab diamonds are real diamonds, not “fakes.” They’re not imitations—they’re just made differently.
Do They Look Cheaper?
Only in price, not in appearance. In fact, many lab diamonds are visually cleaner because they can be grown with fewer inclusions.
What About Resale Value?
It’s true: resale value is lower for now. But trends are changing. As more consumers go lab-grown, resale value may follow.
