What are lab-created diamonds?
Lab-created diamonds (also known as lab-grown or man-made diamonds) are made in a laboratory and are an exceptional mix of master craftsmanship and science—in fact, they have the same optical, chemical, and physical properties as natural diamonds. The core differences are the time they took to form and their origin.
