Lab-Grown Diamonds: Everything You Need to Know

In the world of fine jewelry, diamonds have long been seen as symbols of purity, strength, and timeless beauty. But today, many people are beginning to question where these diamonds come from and at what cost. Traditional diamond mining has raised significant environmental and ethical concerns, leading customers to search for alternatives that align with their values.

Lab-grown diamonds offer exactly that: exceptional beauty, complete transparency, and a future-forward approach to luxury.

Are lab-grown diamonds real?

A lab-grown diamond is a real diamond in every sense:

  • same chemical composition
  • same physical structure
  • same brilliance and durability

The only difference is where it forms.

Instead of growing deep beneath the earth’s surface, these diamonds are created in highly controlled environments using advanced technology that replicates nature’s process.

The result? A diamond with the same magic, but a far clearer origin story.

How are lab-grown diamonds made?

Today, two main techniques are used to grow diamonds:

  • HPHT (High Pressure–High Temperature)
  • CVD (Chemical Vapor Deposition)

Both methods recreate the conditions found deep underground but with full oversight, traceability, and minimal environmental disruption.

Why choose lab-grown diamonds?

The diamond industry has historically been marked by opaque supply chains, dangerous working conditions, and environmental destruction. Mining a single 1-carat diamond can require shifting tens of thousands of pounds of earth, often in vulnerable ecosystems or conflict regions.

Lab-grown diamonds offer a powerful alternative.

They bring transparency, traceability, and responsibility into an industry that desperately needs it.

By moving diamond creation into a controlled environment, we reduce harm to communities and ecosystems and open the door to a more ethical future in fine jewelry.

This isn’t just a trend. It’s a long-overdue transformation.

Are lab-grown diamonds more ethical?

SOCIAL IMPACT

LAB-GROWN

  • Full oversight of the production process
  • Transparent and traceable supply chains
  • Fair pay and safe, regulated working conditions

MINED

  • Complex, opaque and often unethical supply chains, frequently linked to conflict regions
  • Unsafe working environments, extremely low wages, human rights abuses and instances of child labour

ENVIRONMENTAL IMPACT

LAB-GROWN

  • Lower overall energy use
  • Significantly less environmental impact and reduced harm to nearby communities

MINED

  • Leads to soil degradation, large-scale land disruption, deforestation and damage to ecosystems

QUALITY

LAB-GROWN

  • Chemically and physically identical to mined diamonds
  • Evaluated according to the same 4Cs: cut, color, clarity, and carat weight

MINED

  • Achieving the same quality requires sourcing through an extractive process that causes significant environmental harm

AFFORDABILITY

LAB-GROWN

  • More cost-effective, often offering higher quality at the same or even a lower price than mined diamonds

MINED

  • Higher prices due to marketing, extraction, and artificial scarcity

A closer look at the environmental impact

EROSION

Diamond mining often requires removing enormous amounts of soil and rock to reach deposits deep underground. Open-pit mines carve out vast craters that permanently reshape the terrain. In some regions, entire lakes must be drained or rivers redirected to access Kimberlite formations, disrupting natural water systems and causing long-term instability in the soil.

COMMUNITY DISRUPTION

Mining operations frequently take place in rural areas where communities rely on agriculture or local ecosystems for survival. When mining begins, families may be forced to leave their homes with little or no compensation. Those who remain often face unsafe environments, polluted water, and the collapse of traditional sources of income, creating long-term social and economic instability.

ECOSYSTEM DESTRUCTION

The removal of topsoil and vegetation destroys habitats that animals depend on, pushing wildlife out of the region. Fertile land becomes infertile and can no longer be used for farming, leaving the landscape scarred and unproductive. Flooded mining pits collect stagnant water filled with pollutants, harming nearby communities and accelerating the breakdown of local ecosystems.

CARBON EMISSIONS

Extracting diamonds from deep underground requires heavy machinery, explosives, and significant amounts of energy, all of which contribute to greenhouse gas emissions. While lab-grown diamonds also require energy to produce, their manufacturing process can be optimized more easily and is increasingly supported by renewable energy sources. This makes it possible to reduce environmental impact and achieve greater transparency around energy use, offering a more controlled and potentially lower-emission alternative to traditional mining.

Can you tell the difference?

Even expert gemologists cannot distinguish a mined diamond from a lab-grown one with the naked eye. Both are pure carbon, with identical brilliance.

Only specialised instruments can detect subtle structural clues. This is why grading institutes like GIA, IGI evaluate both types using the same standards.

A diamond is a diamond — whether it forms in the earth or in a lab. The difference lies not in the material, but in the way it comes into being.

Is Lab-grown cubic zirconia?

No, cubic zirconia is not a diamond, it contains no carbon, is softer, and looks noticeably different. Lab-grown diamonds, by contrast, are real diamonds with all the same physical and chemical properties as mined stones.

This distinction matters when choosing fine jewelry meant to last a lifetime.

Diamond buying guide

Choosing a diamond doesn’t have to feel overwhelming. Understanding the basics will help you feel more confident, making it easier to find, or even create, a piece that suits you perfectly with a diamond that meets your expectations.

Do your research and choose a trusted brand

Buy from companies that offer transparency, certifications, and real expertise.

It’s essential to understand the background of the company supplying your diamonds. Many brands advertise themselves as trustworthy without providing much proof, which is why speaking with a qualified expert is always a smart first step.

Pick your shape

Each shape reflects light differently, choose the one that fits your style.

Diamonds are evaluated by how effectively their cut facets reflect and refract light. Achieving the ideal proportions, symmetry, and polish requires skilled craftsmanship.

Choose your carat

Carat refers to the weight of a diamond. One metric carat equals 200 milligrams, and each carat is divided into smaller units for accurate measurement. When all other quality factors remain the same, the price of a diamond generally rises with its carat weight. Larger stones cost more, but proportion matters just as much as size.

Choose your stone properties

Diamonds are also assessed for their purity, ranging from stones that appear nearly flawless under magnification to those with internal inclusions and surface blemishes that can be visible to the naked eye. No diamond is completely without imperfections, but the fewer the irregularities, the higher its clarity grade.

Colour is evaluated by looking at how little colour the stone displays. A chemically pure and structurally perfect diamond shows no noticeable hue and is graded on a scale from D (colourless) to Z (light colour).

Where can you buy lab-grown diamonds?

Just like mined diamonds, lab-grown stones are professionally graded and certified. At IRALIS, every diamond above 1 ct is evaluated by leading gemological institutes such as IGI or GIA to ensure full quality assurance. All of our lab-grown diamonds and gemstones are grown using solar energy, hand-selected by our diamond experts, and crafted in Italy by our goldsmiths using recycled gold. Alongside our collection of contemporary fine jewelry designed in Zurich, we also offer a bespoke service that allows you to design a truly personal piece: one created to reflect your uniqueness and accompany you for a lifetime.
