Lab-Grown Diamond vs. Natural Diamond: What’s the Difference?

Diamonds have been a symbol of love, luxury and elegance for centuries. Today, jewellery lovers have more choices than ever — especially with the rise of lab-grown diamonds. At Nafaluxe, we work with both natural and lab-grown stones, and many customers ask: What is the real difference between them?

Let’s explore everything you need to know before buying your next diamond.

What is a Natural Diamond?

A natural diamond is formed deep beneath the Earth over billions of years. Extreme heat and pressure create pure crystalline carbon, which is mined, cut and polished into a diamond.

Key features of natural diamonds:

• 100% formed in nature

• Rare and limited supply

• Each diamond is unique

• Often higher resale value due to rarity

Natural diamonds typically come with reputable certifications such as GIA or IGI, confirming their quality.

What is a Lab-Grown Diamond?

A lab-grown diamond is a diamond created in a high-tech laboratory using advanced technology. The two main methods are:

• CVD (Chemical Vapor Deposition)

• HPHT (High Pressure High Temperature)

These processes replicate the natural diamond formation but in weeks instead of billions of years.

Important to know:

✔️ Same physical, chemical and optical properties as natural diamonds
✔️ Real diamond — not imitation, not cubic zirconia, not moissanite
✔️ Can also be certified by IGI or GIA

Lab-Grown vs. Natural: The Differences

1. Composition

• Natural: Pure carbon formed in nature

• Lab-Grown: Pure carbon grown in a controlled lab environment

👉 Scientists cannot tell the difference without special equipment.

2. Price

Lab-grown diamonds are typically 40% – 70% more affordable than natural diamonds of the same cut, clarity and carat.

This means customers can enjoy:

• Bigger stones

• Higher clarity

• Better colour

for the same budget.

3. Sustainability & Ethics

• No mining

• Reduced environmental impact

• Conflict-free sourcing

Lab-grown diamonds are a great option for customers who want a more ethical jewellery choice.

4. Resale Value

Natural diamonds hold value more consistently due to rarity. Lab-grown diamonds can be resold, but usually at a lower resale price because they can be reproduced.

✔️ False. They are real diamonds with the same carbon structure.

❌ “They look different.”

✔️ False. Even jewellers need special machines to identify them.

❌ “Lab-grown stones have no certification.”

✔️ False. Many lab-grown diamonds come with IGI or GIA certificates, just like natural stones.
