What Is a 3 Carat Lab Grown Diamond?
A 3 carat lab grown diamond is a real diamond created in a controlled laboratory environment using advanced diamond-growing technology. It has the same essential physical, chemical, and optical properties as a natural diamond, offering the brilliance and beauty expected from a genuine diamond.
3 carat refers to the actual weight of the diamond, not its exact visible size. A round 3 carat lab grown diamond will generally be around 9mm in diameter, but the face-up size can vary depending on the shape, cut, and proportions.
Buyers can choose from a selection of shapes, color grades, clarity levels, and certification options to find a 3 carat lab grown diamond that suits their personal style, jewelry design, and budget.
