Your engagement ring is one of the most important purchases you make in your life. Not only is it an investment, but there are a lot of factors you need to decide between. What shape and cut of diamond do you want? How many carats fit into your budget? What setting suits your style the most?

One question that we’ve settled on is that of choosing between a lab-grown and earth-grown diamond. Not only are lab-grown diamonds ethically sourced, but they’re better for your budget too, and yes, they are still real diamonds.

What are lab-grown diamonds? Are lab-grown diamonds considered “real” diamonds?

Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds, and they are a 10 on the Mohs hardness scale — the only difference is their origin.

If you compared a lab-grown diamond to one grown in the earth, would you be able to see a difference? Would a professional be able to see a difference? Visually, lab-grown diamonds and mined diamonds are identical; even to a professional, they would be indistinguishable. In order to differentiate a lab-grown diamond from a mined diamond, the stones would need to be tested using a highly specialised machine. That being said, lab-grown diamonds that are certified by a large lab will have a laser inscription on the girdle of the stone. The laser inscription will indicate “Lab-Grown,” along with the diamond’s certification number.

Costs of lab-grown vs. mined diamonds

Lab-grown diamonds tend to be at least 20-30 percent less than mined diamonds with the same specifications. In fact, a savings of 50-70 percent is not uncommon, particularly when purchasing larger size stones.

Cultivation of lab-grown diamonds

Lab-grown diamonds are formed through two processes: HPHT (High-Pressure High Temperature) and CVD (Chemical Vapor Deposition). HPHT diamonds start as a small diamond seed which is placed into carbon and exposed to extreme temperatures and high pressure — conditions similar to those beneath the earth’s surface. A CVD diamond starts as a thin slice of the diamond seed, which is placed in a highly heated chamber, and filled with carbon-rich gases. Through the magic of technology, carbon bonds with the diamond seed, and it crystallizes. Lab-grown diamonds can be grown in 6-12 weeks’ time.

Why would someone choose a lab-grown diamond over a mined one?

Purchasing a lab-grown diamond over a mined diamond does not compromise anything at all. In fact, with a lab-grown diamond, you get a beautiful, ethically sourced stone for a fraction of the price of a mined diamond. It’s a win-win.

Are lab-grown diamonds certified and graded on the same scale as mined ones?

Yes, lab-grown diamonds are graded using the same standards that are used for mined diamonds. They are graded based on the diamond’s four Cs — color, cut, clarity, and carat. Each diamond is graded by several gemologists at the lab, and the grades are compiled to ascertain a final grade.

Are lab-grown diamonds sustainable?

Unlike traditional mining, which can be detrimental to ecosystems, the production of lab-grown diamonds results in significantly lower environmental degradation. This commitment to sustainability is further highlighted by initiatives like planting a tree for every purchase, enhancing their appeal as an ethical choice.

Why are lab-grown diamonds so popular for engagement rings?

Lab-grown diamonds are increasingly chosen for various types of jewellery, including necklaces, earrings, and bracelets, due to their ethical production and affordability. This makes them an excellent choice for all occasions, from anniversaries to gifts.

Moissanite vs lab-diamond

While similar in appearance to lab diamonds, moissanite differs in composition and price. Moissanite is not a form of diamond but a distinct gemstone with unique properties and typically lower prices. When choosing between moissanite and lab diamonds, consider factors such as brilliance, budget, and personal taste.

Why should I choose a lab-grown diamond for an engagement ring?

Many choose lab diamonds for engagement rings due to their impeccable quality, ethical sourcing, and excellent value. They provide all the brilliance and beauty expected of a traditional diamond at a more accessible price point, aligning with modern values of sustainability and ethical responsibility.

Simulated diamond vs lab-grown diamond

While exploring options, you might encounter terms like 'simulated diamonds.' These are not true diamonds but materials designed to mimic the appearance of diamonds, such as cubic zirconia. It's important to distinguish between simulated diamonds and lab-grown diamonds, which are real diamonds with the same physical and chemical properties as mined diamonds.
