Our Diamond

What are
lab-grown
diamonds?Fine jewelry for the next generation.

For centuries, diamonds have been a symbol of beauty and eternity. Yet today, before that brilliance reaches our hands, the jewelry industry faces real challenges — the environmental impact of mining, the consumption of natural resources, and a lack of transparency around origin.

Lab-grown diamonds are a new choice, made for the times ahead. Grown without mining, they are real diamonds with the same chemical composition, crystal structure, hardness, and brilliance as natural diamonds.

PRMAL chooses lab-grown diamonds to create jewelry that can be passed on to the future without compromising on beauty. Reverence for nature, uncompromised beauty, and responsibility for what comes next — this is what we believe fine jewelry for the next generation should be.

DifferencesThe same brilliance, a different origin.

The difference between lab-grown and natural diamonds lies in their origin.

Natural diamonds form deep within the earth over immense spans of time. Lab-grown diamonds are grown by scientifically recreating that natural environment, developing the same carbon crystal structure.

As a result, their physical and chemical properties as diamonds — hardness, refractive index, dispersion, thermal conductivity — are identical to natural diamonds. Leading gemological institutes grade them by the same standards, and the two cannot be told apart without specialized instruments.

The only difference is where they were born. A diamond is a diamond.

Nature's time, recreated by science.

Lab-grown diamonds do not replace the workings of nature. They recreate, through modern science, the environment in which diamonds form deep within the earth over long spans of time.

Starting from a small diamond seed, carbon atoms accumulate little by little over weeks to months — under high temperature and pressure, or deposited from a carbon-rich gas — growing into a single diamond.

Each diamond is then carefully cut and polished by skilled artisans, finished into jewelry with a brilliance all its own.

SustainabilityThe value of choosing the future.

We keep the beauty of diamonds intact while rethinking our impact on the environment — with reverence for the beautiful minerals nature has nurtured over millions of years.

Because lab-grown diamonds require no mining, they are diamonds for a new era, created with less impact on the land, drawing on fewer natural resources. Production powered by renewable energy is further reducing CO₂ emissions and water use.

Passing beautiful jewelry on to the future, and passing beautiful nature on to the future — at PRMAL, we believe both are our mission.

No mining required

A more sustainable choice,
made with the earth in mind.
The same quality as natural diamonds

Beauty, brilliance, and durability
identical to natural diamonds.

expand creative freedom.

More freedom for beauty.

Lab-grown diamonds open new possibilities not only for beauty, but for design.

Large diamonds and distinctive shapes that are exceptionally rare in nature can be brought to life in jewelry with far greater freedom.

The intricate, delicate, organic forms drawn by nature are at the heart of PRMAL's design. Being able to express them without compromise is another value that lab-grown diamonds bring.

A new brilliance to pass on.

Jewelry is not a fleeting beauty; it lives alongside you through the years. That is why PRMAL believes in taking responsibility for the future, down to the very materials we use.

True brilliance, and respect for nature. Holding both close, we create jewelry to be passed on to the next generation.
