What is the difference between lab-grown and natural diamonds?

That is a question we are often asked at Viclara – and we understand why. Both natural and lab-grown diamonds exude the same timeless beauty and elegance. But even though they look almost identical, they have very different origins and stories.

If you want to make an informed choice when investing in a diamond – whether it’s for an engagement ring, earrings, or a piece of jewelry for yourself – it’s worth knowing the difference between lab-grown and natural diamonds. Here we explore everything from price and sustainability to certification and quality.

Natural diamond – created deep within the earth

A natural diamond originates deep beneath the earth’s surface, where it forms over millions of years through intense pressure and high temperatures. The diamonds are brought to the surface by geological processes and subsequently mined in various locations around the world.

The millions of years of formation make natural diamonds truly special. In addition, each stone is unique – a masterpiece of nature. That is precisely why many choose a natural diamond for life’s most significant moments.

Lab-grown diamond – created with precision

A lab-grown diamond is produced using advanced technology in modern laboratories. Here, nature’s own process is imitated using either HPHT (High Pressure High Temperature) or CVD (Chemical Vapor Deposition).

The result is a diamond that is chemically, physically, and optically identical to a natural diamond. These are not imitations like cubic zirconia or moissanite – but genuine diamonds created under controlled conditions.

Price – an important difference

When we talk about the difference between lab-grown and natural diamonds, price is often a key point. Lab-grown diamonds typically cost 30–40% less than natural ones – without compromising on quality or aesthetics.

This is primarily due to:

• Less dependence on mining
• More predictability in production
• Increasing availability

By choosing a lab-grown diamond, you often get more for your money – both in terms of size and impression – compared to natural alternatives in the same price range.

Sustainability and responsible origin

Sustainability is an important factor for many who choose jewelry at Viclara – and here, lab-grown diamonds often have an advantage. They require no mining and thus minimize the ecological footprint, and they are produced without involving vulnerable local communities.

However, that does not mean that natural diamonds are necessarily unethical. Thanks to initiatives such as the Kimberley Process, many natural diamonds today are mined under responsible conditions – both environmentally and socially.

At Viclara we take pride in transparency. We work only with suppliers who can document both sustainability and ethical origin – regardless of the type of diamond.

Certification – your guarantee of authenticity

Whether the diamond is natural or lab-grown, certification is essential to document its quality and origin. Renowned gemological institutes such as GIA (Gemological Institute of America) and IGI (International Gemological Institute) assess diamonds based on:

• Cut
• Color
• Clarity
• Carat

All Viclara’s diamond jewelry comes with a certificate, so you can be confident in your investment. That is our guarantee of quality – and your security.

Can you see the difference?

A frequent question among our customers is: Can you see the difference between a lab-grown and a natural diamond? The answer is simple – no, not with the naked eye. Even professionals need special equipment to distinguish between the two.

That is why the choice is not just about appearance, but also about values. What matters most to you – nature’s primal force or modern technology and sustainability?
