The rise of lab-grown diamonds has reshaped the jewellery industry — especially in Australia, where ethically sourced and budget-conscious choices are highly valued.
But is a lab-grown diamond better than a natural diamond?
As a manufacturing jeweller, we get this question daily. The answer depends on your budget, values, and intentions.
Let’s break down the facts, from science and sustainability to resale value and visual differences.
What Is a Lab-Grown Diamond?
Lab-grown diamonds (also called synthetic or man-made diamonds) are created in a controlled lab environment, not mined from the earth.

Certification Matters
Both lab-grown and natural diamonds should come with a grading certificate from a trusted lab like GIA or IGI.
Look for:
- Carat, Cut, Colour, Clarity
- Growth method (CVD or HPHT for lab-grown)
- Laser inscription number on the girdle.

Manufacturing Jeweller’s View: Many clients choose lab-grown for ethical peace of mind, especially younger buyers and same-sex couples seeking something meaningful and modern
Resale & Investment
Natural diamonds typically:
- Hold value over time
- Can be reset, resold, or traded in
Lab-grown diamonds:
- Currently drop in value after purchase
- Seen more as a fashion piece, not a long-term asset
"If your priority is romance, sparkle, and budget, lab-grown is perfect. If it's heirloom and investment, stick with natural."
