Earth’s Natural Process, Perfected
Unsaid exclusively uses lab-grown diamonds, recreating Earth’s billion-year process in just 600 hours. These diamonds share the same chemical composition, brilliance, and durability as mined stones without the environmental cost. For every carat, a mined diamond requires 7300 liters of water and emits 160kg CO2. In comparison, every carat of lab-grown diamonds grown with renewable energy requires just 0.3 liters of water and 12kg of CO2. (Trucost Report 2017).
Pure and Prized
The only difference between mined and lab-grown diamonds is their method. Unsaid diamonds are Type IIa—the purest and most sought-after type, free from chemical impurities and composed entirely of carbon. Only 5% of mined diamonds meet this standard.
Created in a process powered by renewable energy, our diamonds are grown by placing a tiny diamond seed in a sealed chamber heated to 800°C. Methane, hydrogen, and carbon gases ionize into plasma, depositing pure carbon onto the seed and forming a diamond crystal over time. This method replicates nature’s process without harming the planet, producing gems with the same scintillation, brilliance, and durability as mined stones.
Avant-garde Creation
Lab-grown diamonds offer unparalleled creative freedom, enabling precise control over size, cut, and color. The Maison designs each piece and grows diamonds to exact specifications, producing innovative and extraordinary jewelry.
