Lab Grown Vs Natural Diamonds: What's the Difference?
The debate between lab-grown and natural diamonds is no longer confined to industry experts. Today’s consumers want clarity — quite literally — when deciding what kind of diamond is right for them. Whether you’re buying an engagement ring, a statement necklace, or simply curious about diamond jewellery trends, this guide will walk you through every key difference in detail.
What Are Lab-Grown Diamonds?
Lab-grown diamonds, also known as synthetic or man-made diamonds, are diamonds created in controlled laboratory environments. These diamonds are not imitations. They are chemically, physically, and optically identical to natural diamonds.
The primary difference lies in their origin — lab-grown diamonds are cultivated using advanced technology, whereas natural diamonds are formed beneath the Earth’s surface over billions of years.
How Are Lab-Grown Diamonds Made?
Lab-grown diamonds are produced using two main methods:
-
HPHT (High Pressure High Temperature): Mimics the natural conditions under which diamonds form in the Earth.
-
CVD (Chemical Vapour Deposition): A newer method where carbon gas is broken down in a chamber, and carbon atoms form diamond crystals layer by layer.
Both techniques create real diamonds, just in months instead of millennia.
Are Lab Grown Diamonds Expensive?
Lab-grown diamonds are generally 30% to 50% cheaper than natural diamonds of similar size and quality. Because they are more accessible to produce, their market value is lower, making them ideal for buyers looking for high brilliance without the high price tag.
How Do We Know If We Have Lab-Grown Diamonds?
Lab-grown diamonds are difficult to detect with the naked eye. Even professionals may struggle without the right equipment. However, certified lab-grown diamonds are laser-inscribed and come with a grading report from a reputable gemological lab (like IGI or GIA) stating their origin.
What Are Natural Diamonds?
Natural diamonds are formed deep within the Earth under intense pressure and heat. It takes between 1 to 3 billion years for a natural diamond to crystallise. Once mined, these diamonds are cut and polished into the stunning gemstones we see in jewellery.
Each natural diamond is unique, shaped by the natural forces of the planet — making it a symbol of timelessness and rarity.
Are Natural Diamonds Expensive?
Yes. Natural diamonds are more expensive than lab grown ones due to their rarity and the cost involved in mining, cutting, certifying, and distributing them. Factors like the diamond’s clarity, carat, cut, and colour all influence price — but even at smaller sizes, natural diamonds command premium prices.
How Do We Know If We Have Natural Diamonds?
Like lab-grown diamonds, natural diamonds come with certification. Look for documentation from GIA, HRD, or IGI stating that your diamond is natural. If unsure, a reputable jeweller can test your diamond using advanced tools that differentiate between lab-grown and mined stones.
How Are They Different?
| Feature | Lab Grown Diamonds | Natural Diamonds |
|---|---|---|
| Origin | Created in labs | Formed naturally over billions of years |
| Price | 30-50% more affordable | More expensive due to rarity |
| Environmental Impact | Lower carbon footprint | Mining can be environmentally taxing |
| Resale Value | Lower | Higher resale and investment value |
| Appearance | Identical | Identical |
| Certification | Yes (e.g., IGI, GIA) | Yes (e.g., GIA, HRD) |
Which Should You Choose: Lab Grown or Natural?
Choosing between lab grown and natural diamonds depends entirely on your priorities.
Choose Lab Grown Diamonds if:
-
You want a larger stone for your budget.
-
Ethical sourcing and environmental impact are important to you.
-
You don’t prioritise long-term resale value.
Choose Natural Diamonds if:
-
You value tradition, rarity, and long-term investment.
-
You’re purchasing heirloom-quality diamond jewellery.
-
You want a diamond with millions (even billions) of years of history.
Ultimately, both lab grown and natural diamonds have their merits. The right choice is the one that aligns with your values, your budget, and the story you want your jewellery to tell.
Conclusion
The world of diamond jewellery is no longer one-size-fits-all. Lab grown diamonds offer innovation, affordability, and sustainability, while natural diamonds carry the allure of Earth’s ancient treasures. Knowing the facts empowers you to make a decision that suits both your heart and your wallet.
Whichever you choose, make sure it comes certified, ethically sourced, and worthy of the moment it represents.
FAQs: Lab Grown vs Natural Diamonds
Q: Are lab grown diamonds real diamonds?
A: Yes. Lab grown diamonds are chemically and physically identical to natural diamonds. They are not simulants like cubic zirconia.
Q: Will a jeweller know if my diamond is lab grown?
A: A professional jeweller with proper testing tools can determine whether a diamond is lab-grown or natural.
Q: Do lab-grown diamonds lose their sparkle over time?
A: No. Lab-grown diamonds are just as durable and brilliant as natural diamonds.
Q: Can I resell a lab-grown diamond?
A: Yes, but they generally have lower resale value compared to natural diamonds.
Q: Which is better for the environment?
A: Lab-grown diamonds have a lower environmental impact because they do not require mining.
Q: Are natural diamonds rarer than lab-grown ones?
A: Yes. Natural diamonds are limited in quantity and take billions of years to form, making them rarer.
