What Is A Lab Grown Diamond?

Lab-grown diamonds, also known as synthetic or cultured diamonds, are not imitations but authentic diamonds with a twist of human ingenuity. They challenge the traditional narrative of diamond formation, bringing a blend of technological prowess and additional considerations to the forefront. In this blog, we’ll uncover the story behind lab-grown diamonds, exploring their significance and impact on the jewellery industry and our relationship with precious stones.

What Exactly Is A Lab-Grown Diamond?

The lab-created diamond is a type of genuine diamond created in a controlled laboratory setting and is a testament to modern technological advances and ethical practices. Unlike imitations, these are real diamonds with the same crystal structure and properties as those formed naturally. They represent a significant shift in diamond production, combining innovative technology with additional considerations to offer a responsible alternative in the gemstone market.

Are Lab-Made Diamonds From Real Diamonds?

Lab-grown diamonds are true diamonds – sharing the same physical, chemical, and visual properties as their natural mined diamonds. They’re created from scientific precision and creative vision, where a diamond seed is crafted into a full diamond using conditions that mimic the Earth’s mantle. But the question arises: are these lab-made diamonds on par with natural ones?

The answer lies in their creation. Each lab-grown diamond begins as a tiny carbon seed, which grows atom by atom under controlled environmental conditions, crystallising into a diamond that radiates with the same brilliance and hardness as a mined diamond. This process not only preserves the intrinsic qualities of a natural diamond but also opens new vistas of ethical and sustainable choices.

What Are The Differences Between Lab-Grown And Natural Diamonds?

There’s a fascinating dichotomy between lab-grown and natural diamonds. While both share the charm and grandeur that diamonds are renowned for, their journey from carbon to coveted gemstones are vastly different, each with its own narrative. Natural diamonds are nature’s masterpieces, formed under the immense pressure and heat of the Earth’s mantle, each bearing unique stories of geological history. This type of diamond holds its value when made into an engagement ring, if not increasing over time.

However, whilst lab-grown diamonds appeal due to their lower price bracket, they’re less likely to hold their value, often decreasing over time. At Alicia J, our policy is that we don’t re-purchase lab diamonds because their investment value decreases. Whereas mined diamonds, we would consider, as their investment value increases over time.

Selecting the right diamond for you will depend on your own unique circumstances. Consider outlining why you’re making the investment. Is it for the appearance of diamond engagement rings? Or is it a piece to pass down throughout the generations? Lab-created diamonds will offer a way to achieve the diamond look but at a fraction of the cost. However, natural diamonds are timeless and will reflect your investment in the years to come.

Why Should You Choose A Lab-Grown Diamond?

Lab-grown diamonds have emerged as a choice that combines modern sensibilities with timeless elegance. Let’s explore the benefits of lab-created diamonds in more depth:


One of the most compelling reasons to choose a lab-grown diamond is its sustainability. These diamonds represent a leap forward in eco-conscious luxury. The controlled conditions in which they are produced not only use fewer natural resources but also significantly reduce ecological disruption. Opting for a lab-grown diamond, you embrace a future where luxury and environmental considerations coexist harmoniously.

Good Value

Lab-grown diamonds are an exceptional choice when it comes to value. They offer the splendour and durability of traditional diamonds but at a more accessible price point. This affordability does not compromise quality; instead, it opens the door to exquisite, high-quality diamonds that might otherwise be out of reach. Lab-grown diamonds allow one to own a larger, more brilliant stone for the same investment or enjoy the luxury of fine diamond jewellery without the higher price point.

They Are Just As Real As Natural Diamonds

At their core, lab-created diamonds are every bit as real as natural diamonds. They share the same chemical composition, physical properties, and beauty. The only difference lies in their origin – one from the depths of the earth and the other from the precision of human innovation. Lab-grown diamonds undergo the same rigorous grading and certification processes as natural diamonds, ensuring their authenticity and quality. Choosing a lab-grown diamond means embracing quality and a genuine, modern-day treasure.

As we draw this exploration of lab-grown diamonds to a close, it becomes evident that these stones are more than just a marvel of modern science; they symbolise a new era in luxury jewellery. These gemstones represent a conscious choice for a future where luxury is defined not just by appearance but by the values it upholds. As we move forward, lab-grown diamonds stand as luminous testimonies to innovation and thoughtful luxury, promising to illuminate the path of the jewellery world with their brilliance and ethical charm.

Frequently Asked Questions

We’ve answered some of the most frequently asked questions about lab-grown diamonds below:

Is A Lab-Grown Diamond A Real Diamond?

Lab-grown diamonds are real diamonds; they possess the same chemical composition, physical properties, and crystalline structure as natural diamonds. The main difference lies in their origin.

While natural diamonds have been formed for billions of years in the Earth’s mantle, lab-grown diamonds are created in controlled laboratory environments using advanced technological processes and diamond simulants. This distinction does not diminish their authenticity; lab-grown diamonds exhibit the same brilliance, hardness, and durability as their natural counterparts, making them genuine diamonds in their own right.

Are Lab-Grown Diamonds Worth It?

Lab diamonds offer significant value, both in terms of cost and ethics. They are typically priced lower than natural diamonds, making them an attractive option for those seeking the luxury of a diamond at a more accessible price point for their engagement rings. Natural and lab diamonds are excellent choices, but it depends on your unique requirements.

Do Lab Diamonds Last Forever?

Like natural diamonds, lab-grown diamonds are incredibly durable and among Earth’s hardest substances. This remarkable hardness means that, with proper care, lab-grown diamonds can indeed last forever. They are resistant to scratching, chipping, and breaking under normal wear and tear, making them a lasting choice for jewellery.

However, it’s important to note that they should be treated with care and occasionally inspected by a professional jeweller to ensure their settings remain secure and the diamond retains its brilliance. Their longevity, combined with their ethical and aesthetic appeal, makes lab-grown diamonds a timeless choice.

Can a jeweller tell if a diamond is lab-created?

Specialised equipment and advanced training can enable a jeweller to identify a lab-grown diamond. Such expertise often involves examining the diamond for specific growth patterns or trace elements of the laboratory creation process. Some lab-grown diamonds are also laser-inscribed with a microscopic identifier, indicating their lab-created origin. Therefore, it’s challenging for a jeweller to tell the difference without specialised equipment, but it’s not impossible.

How do machines detect lab-grown diamonds?

Machines utilise advanced technology to detect a lab diamond and identify the unique characteristics and growth patterns not typically found in natural diamonds. For example, in infrared analysis, certain lab-grown diamonds exhibit distinct fluorescence patterns under UV light or specific absorption spectra. These sophisticated machines are designed to pinpoint subtle differences at the molecular level, enabling them to distinguish between diamonds grown in a lab and those formed naturally over thousands of years. This technological precision ensures the accurate identification and certification of lab-grown diamond jewellery.
