Lab Grown vs Natural Diamond

Understand the real differences between earth-mined and laboratory-grown diamonds — so you can choose with confidence.

Natural and lab-grown diamonds may look similar, but natural diamonds are rare and precious, whereas lab-grown diamonds are created artificially using technology and equipment. Both possess the same brilliance and beauty — the right choice simply depends on your values, budget, and vision.

Overview

Natural vs Lab-Grown Diamonds: Key Differences

The difference between natural and lab-grown diamonds is quite significant, despite their similar look and appearance. Natural and lab-grown diamonds may look similar, but natural diamonds are rare and precious, whereas lab-grown diamonds are created artificially using technology and equipment.

Both natural and lab-grown diamonds, when used in making jewellery, may look similar and may possess similar brilliance and beauty, but natural diamonds are considered precious and valuable, whereas lab-grown diamonds are more affordable and may be purchased for those who want to purchase a larger diamond at a lower price.

The Science

How Can You Tell the Difference Between Lab Grown and Earth-Mined Diamonds?

Lab grown diamonds are identical to those found in nature. They have the exact same chemical makeup, and specialist laboratory equipment is needed to tell lab diamonds from natural diamonds.

When looking to discern earth-mined from lab grown diamonds, specialists look for nitrogen within the stone. Lab diamonds contain no nitrogen, whereas natural diamonds pick up tiny amounts of trace elements as they form.

For everyday wear and to the naked eye, the two are completely indistinguishable. Both will dazzle equally — that is the true beauty of both choices.

Common Questions

Frequently Asked Questions

Yes — absolutely. Lab-grown diamonds are real diamonds in every sense. They share the same chemical composition (pure crystalline carbon), the same hardness (10 on the Mohs scale), and the same optical properties as natural diamonds. They are certified by IGI and GIA on the same 4C grading scale: Cut, Colour, Clarity, and Carat.
Yes. Both natural and lab-grown diamonds score 10 on the Mohs hardness scale — the highest possible rating. They are equally resistant to scratching and perfectly suited for everyday jewellery, including engagement rings and wedding bands worn daily for decades.
Neither is objectively better — it depends on your priorities. If you value rarity, heritage, and long-term investment, a natural diamond is ideal. If you prefer a larger stone or a lower price point while still getting certified quality, lab-grown is an excellent choice. Both are exquisite.
Lab-grown diamonds currently hold lower resale value compared to natural diamonds, as they are reproducible and not rare. Natural diamonds have a more established secondary market. However, if resale is not your primary concern, lab-grown diamonds offer outstanding value for money.
