Lab-grown diamonds
EARTH’S NATURAL PROCESS, PERFECTED
For centuries, diamonds have symbolized strength, brilliance, and timeless beauty. Traditionally, these rare gems are formed deep within the Earth's mantle and take billions of years under immense heat and pressure to rise to the surface. Today, Unsaid Paris recreates this natural process in a controlled environment, growing diamonds in just 600 hours while ensuring unparalleled purity and sustainability. Our lab-grown diamonds possess the same chemical composition, structure, and optical properties as mined diamonds, yet they come without traditional extraction’s environmental or ethical costs. A mined diamond requires an astonishing 7,300 liters of water and generates 160 kg of CO₂ per carat, contributing to land degradation and carbon emissions. By contrast, every carat of Unsaid’s lab-grown diamonds, cultivated with renewable energy, consumes only 0.3 liters of water and emits 12 kg of CO₂—a revolutionary step toward sustainable luxury (Trucost Report 2017).
PURE AND PRIZED: THE SCIENCE OF LAB-GROWN DIAMONDS
The primary distinction between lab-grown diamonds and mined diamonds is their origin. While mined diamonds form under the Earth’s surface over millennia, Unsaid’s diamonds are grown using a precise scientific process that mirrors nature’s formation. The result is type IIa diamonds, the purest and most sought-after diamond classification, free from nitrogen or chemical impurities. Only 5% of the world’s mined diamonds meet this exceptional standard.
THE GROWTH PROCESS: CUTTING-EDGE TECHNOLOGY MEETS NATURE’S BLUEPRINT
Our diamonds are created using plasma-enhanced chemical vapor deposition (CVD), which begins with a microscopic diamond seed placed inside a sealed chamber. This chamber is then heated to 800°C, creating conditions similar to the Earth’s mantle. A mixture of hydrogen, methane, and carbon-rich gases is introduced. Unsaid extracts from natural animal gas and ionize into plasma, breaking down the gases so pure carbon atoms can bond to the seed, gradually forming a rough diamond crystal. Over weeks, the crystal grows layer by layer, achieving exceptional purity and brilliance. Once fully formed, the diamonds undergo precise cutting and polishing by master artisans to enhance their fire, scintillation, and light dispersion. Every Unsaid diamond is assessed using the same industry standards that evaluate mined diamonds, ensuring exquisite quality and unmatched beauty.
SUSTAINABILITY & ETHICAL LUXURY: THE FUTURE OF FINE JEWELRY
The shift toward lab-grown diamonds represents more than an evolution in craftsmanship—it is a paradigm shift toward ethical luxury. Diamond mining has historically been linked to deforestation, habitat destruction, and carbon-intensive operations. Additionally, mining practices have long raised ethical concerns, from unsafe working conditions to conflict diamonds.
Unsaid Paris is committed to pioneering the future of luxury, where artistry and sustainability coexist in the fine jewelry world. Our diamonds are:
- - 100% conflict-free, ensuring traceability from creation to final design.
- - Grown using renewable energy, reducing carbon emissions and environmental impact.
- - Water-efficient, using a fraction of the resources required for mined diamonds.
By choosing lab-grown diamonds, we preserve Earth’s resources and redefine the standards of modern luxury, one that values beauty without compromise.
A lab-grown diamond is just that: a diamond. It has the exact same crystal structure and chemical composition as a mined diamond.
AVANT-GARDE CREATION: UNPARALLELED ARTISTRY AND INNOVATION
Lab-grown diamonds open new possibilities for creative expression, allowing greater control over size, cut, color, and clarity. Unlike mined diamonds, which are limited by natural availability, Unsaid’s precisely grown diamonds offer designers the freedom to push boundaries and create never-before-imagined shapes. Every Unsaid creation is meticulously designed with optimal precision and avant-garde artistry, ensuring the light dances across each facet with mesmerizing brilliance. This control over the diamond-growing process allows us to craft exclusive, unparalleled designs, transforming classic creations into modern heirlooms.
CRAFTED TO INSPIRE: THE UNSAID DIFFERENCE
Unsaid Paris believes that a diamond is more than a jewel—it is a story waiting to be told. From the moment a diamond seed is placed in the chamber to its final masterful cut, every stage is imbued with artistry, science, and sustainability. Our vertically integrated approach ensures that each diamond meets our exacting standards, resulting in luxury jewelry that is as conscious as it is captivating.
