What Are Lab-Grown Diamonds?
Lab-grown diamonds are diamonds created in controlled conditions. Chemically and optically they are diamonds — with a different origin story than mined stones.
Diamond, not imitation
Lab-grown diamonds share the same crystal structure as natural diamonds. They can be graded for cut, color, clarity, and carat, and set into fine jewelry just as mined stones are.
Why Asteria chooses them
Lab-grown diamonds allow us to focus on design, color, and craftsmanship — including vivid colored stones — while keeping each piece transparent about origin and certification.
