Natural diamonds are formed over billions of years deep below the earth’s surface, under extreme pressure and high temperature. They rise and become accessible by volcanic eruption.
Lab-grown diamonds are produced in a lab within weeks or months, using specialized technology that mimics the extreme heat and pressure of a natural diamond’s growing environment.
Lab-grown diamonds (also referred to as engineered, man-made, or lab-created diamonds) possess the same optical, chemical, and physical properties as a natural diamond. Natural vs. lab-grown diamonds are virtually indistinguishable to the untrained eye. What sets them apart, however, are their origin and the time they took to form.
