What are lab-grown diamonds? Differences, advantages, and what to look out for

Lab-grown diamonds—also called laboratory diamonds or synthetic diamonds—are genuine diamonds grown in a laboratory under controlled conditions. They are chemically, physically, and optically identical to naturally grown diamonds—the only difference lies in their origin.

How are lab-grown diamonds created?

There are two scientific processes for producing laboratory diamonds:

Wie werden im Labordiamanten hergestellt? Mit Verfahren wie HPHT und CVD werden synthetische Diamanten hergestellt.

1. HPHT – High Pressure High Temperature

This imitates the natural growth process: a small diamond nucleus is crystallized under high pressure and high temperature.

2. CVD – Chemical Vapor Deposition

In this process, diamonds grow layer by layer from a gas plasma – a particularly controlled process that is widely used in the jewelry industry.

Important to know: Both methods produce diamonds with the same hardness, clarity and brilliance as natural stones.

Difference between lab-grown and natural diamonds

Are laboratory diamonds/lab-grown diamonds real?

Yes – and that's one of the biggest misconceptions. Lab-grown diamonds are not imitations like zirconia or moissanite, but genuine diamonds. They are made of pure carbon, are just as hard (Mohs hardness 10), and are even certified according to the same standards as natural diamonds (e.g., GIA, IGI).

Only with special laboratory equipment can it be determined whether a diamond comes from the earth or from the laboratory.

Are lab-grown diamonds more sustainable?

Yes – significantly. Natural diamond mining pollutes soils, waterways, and entire ecosystems. Millions of tons of rock are moved, CO₂ is emitted, and in some regions, people are employed under unfair conditions.

Lab-grown diamonds require energy – but no water, no blasting, no mines.

At Ilikoez, our diamonds come exclusively from laboratories with a focus on transparency and sustainable energy use – for diamonds that are not only beautiful, but also produced in a nearly climate-neutral way and certified responsible.

Why buy lab diamonds?

Lab-grown diamonds—also called lab-grown or synthetic diamonds—are genuine diamonds with the same hardness, brilliance, and beauty as natural diamonds. The only difference is their origin: They are created in laboratories— without mining, environmental destruction, or questionable supply chains .

1. Quality without compromise

Lab-grown diamonds are chemically and optically identical to natural diamonds. At Ilikoez, you only get certified lab-grown diamonds according to the 4Cs (carat, cut, color, and clarity) – ideal for high-quality engagement rings, earrings, and custom pieces. Your design without compromise.

2. Affordable price – more carats for your money

A lab-grown diamond often costs 30–50% less than a natural diamond of the same quality. This means a larger diamond for the same budget —perfect for those who don't want to compromise on design.

3. Sustainability & Fairness

Anyone who buys lab-grown diamonds is consciously choosing to avoid mining, child labor, and environmental destruction. Our diamonds are produced in a virtually climate-neutral manner and are certified accordingly.

4. The modern choice for conscious buyers

More and more people are consciously choosing lab-grown diamonds when buying engagement rings or special diamond jewelry – for a good feeling without sacrificing luxury.

FAQ – Frequently asked questions about lab-grown diamonds

Yes! Lab-grown diamonds, just like natural diamonds, are made of pure carbon. They are chemically, physically, and optically identical to mined diamonds. The only difference is where they were created: in a lab instead of the Earth's crust.

Absolutely. Lab-grown diamonds are beautiful, ethically sourced, and durable—and offer the highest quality at a better price than natural diamonds. They also allow you to choose larger stones or special cuts like oval, pear, or marquise —without compromising on clarity or brilliance. It's no wonder, then, that more and more couples are consciously choosing lab-grown diamond engagement rings.

Yes, lab-grown diamonds often cost up to 30–50% less – especially for larger stones. This is because they are more efficient to produce without expensive mining.

There are two processes: HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Deposition) . Both mimic the natural growth process – controlled, precise, and sustainable.

As with natural diamonds, the resale value is lower than the purchase price. The absolute loss is usually lower for lab-grown diamonds.

Let’s take a rough comparison between natural diamonds and lab-grown diamonds:

A ring with a natural diamond, for example, costs €20,000. You might get €5,000 for it at resale—a loss of €15,000. (Plus, the demand for lab-grown diamonds is currently soaring!)

A comparable ring with a lab-grown diamond costs about €5,000. The resale price is around €1,000—a loss of €4,000.

💡 The percentage loss in value is high for both – but with lab diamonds the loss remains significantly lower in absolute terms.

But let's be honest: Very few people buy a diamond ring to resell it. It's all about the emotion, the love, the memories, and the significance of a special moment. 💛 The true value lies not in the resale, but in the feeling a piece of jewelry evokes.

Lab-grown diamonds give you the freedom to choose consciously – with a clear conscience and without compromising on beauty or quality.

Not with the naked eye, magnifying glass, or jeweler's tools. Only special spectroscopy in laboratories can determine the origin based on growth structures or nitrogen distribution.

Yes. No mining, no environmental destruction, no conflicts. Our stones come from virtually climate-neutral laboratories that operate with renewable energy.

Yes. At Ilikoez, you only receive lab-grown diamonds of the highest quality and transparency. Starting at 0.3 carats (brilliants) or 0.5 carats (fancy shapes), we provide you with an official certificate—e.g., from IGI or GIA —grading according to the four Cs: cut, clarity, color, and carat .

A lifetime – and longer. They are just as hard and durable as mined diamonds; they are identical.

Conclusion: A real diamond – only more conscious💎🌱

Lab-grown diamonds are no longer a vision of the future – they are the modern answer to the desire for genuine, sustainable jewelry.

So if you are looking for a special diamond that is not only aesthetically pleasing but also ethically sound, then a lab-grown diamond is the right choice.
