The Rise of Lab-Grown Diamonds: Quality, Ethics, and Choice

Stephen Alan's Jewellers - The Jewellery Blog

We’re pleased to announce that lab-grown diamonds are now part of our offering here at Stephen Alan’s. While we’ve historically championed natural diamonds—as many traditional jewellers have—recent advancements in technology, customer preferences, and market transparency have made it clear: lab-grown diamonds now offer a compelling and credible alternative.

In this article, we look at what lab-grown diamonds are, how they compare to natural diamonds, and why we’re proud to now include them in our collection.

What Are Lab-Grown Diamonds?

Lab-grown diamonds are real diamonds—chemically, physically, and optically identical to those found in nature. The key difference lies in how they’re formed.

While natural diamonds develop over billions of years beneath the Earth’s surface, lab-grown diamonds are created in a controlled environment using two main processes:

• HPHT (High Pressure High Temperature): This method replicates the conditions of the Earth’s mantle, using high pressure and heat to form a diamond around a small ‘seed’.

• CVD (Chemical Vapour Deposition): A diamond seed is exposed to carbon-rich gases at high temperatures, allowing carbon atoms to gradually form the structure of a diamond.

Once complete, the finished product is visually and structurally indistinguishable from a mined diamond, even to the trained eye—unless examined using specialist equipment.

Are Lab-Grown Diamonds Certified?

Yes. Just like natural diamonds, lab-grown stones are graded according to the Four Cs—cut, colour, clarity, and carat—by respected gemmological laboratories such as the IGI or GIA.

Each lab-grown diamond we offer at Stephen Alan’s comes with a certificate of authenticity, ensuring you know exactly what you’re purchasing.

Why Choose Lab-Grown Diamonds?

There are several reasons why lab-grown diamonds are becoming an increasingly popular choice:

✔️Greater Value

Lab-grown diamonds typically cost 30–40% less than their mined counterparts, meaning you can often choose a larger or higher-grade stone within your budget.

✔️Sustainability

Without the need for deep-earth mining, lab-grown diamonds offer a more environmentally conscious option. While energy use varies between manufacturers, many are making strides toward clean energy production.

✔️Traceability & Ethics

With a clear and transparent production process, lab-grown diamonds eliminate the concerns associated with conflict diamonds and complex supply chains.

✔️Beauty & Brilliance

Quite simply, lab-grown diamonds are stunning. Their clarity and sparkle are on par with the finest natural diamonds.

Are They “Less Special”?

This is often the biggest question—and it comes down to personal perspective. Natural diamonds carry with them a deep history, formed over billions of years and brought to light by intricate geological processes. For many, this backstory adds sentimental and symbolic value.

On the other hand, lab-grown diamonds represent a more modern narrative—one of innovation, sustainability, and thoughtful design. They are no less real, and for many, no less meaningful.

At Stephen Alan’s, we believe both options have their place. They simply tell different stories.
