Lab-Grown vs Natural Diamonds: What's the Difference?

Are lab-grown diamonds real diamonds?

Yes. A lab-grown diamond is a real diamond — pure crystallised carbon with the same hardness, sparkle and fire as a mined one. It is not a simulant like cubic zirconia or moissanite, which are different materials that only look diamond-like. Independent labs such as IGI and GIA grade lab-grown diamonds on the very same scale as natural stones.

The only real difference is origin. A natural diamond formed over billions of years deep in the earth; a lab-grown diamond is created in a few weeks in a controlled facility that recreates those same conditions of heat and pressure.

How they compare

• Appearance: identical to the naked eye — even a jeweller needs specialised equipment to tell them apart.
• Quality: both are graded on the same 4 Cs (cut, colour, clarity, carat).
• Price: lab-grown typically costs significantly less for the same size and quality, so your budget buys a larger or higher-grade stone.
• Ethics & environment: lab-grown avoids mining, and reputable growers can trace every stone's origin.
• Resale: like most jewellery, neither holds its full retail value second-hand — buy a ring to wear and love, not as an investment.

Which should you choose?

There's no wrong answer — it comes down to what matters most to you. If you want the largest, brightest stone for your budget and value a traceable, mining-free origin, lab-grown is a compelling choice. Every diamond in our range is lab-grown and IGI-certified, set by hand in recycled gold and platinum.
