Frequently Asked Questions
Lab-grown diamonds, also called lab-created diamonds, are real diamonds produced in a laboratory using advanced technology that replicates the natural diamond-forming process. They have the same chemical, physical, and optical properties as mined diamonds. Lab-grown diamonds are made using HPHT (High Pressure High Temperature) or CVD (Chemical Vapor Deposition) methods. Since they don’t require mining, they are an ethical and eco-friendly alternative to traditional diamonds.
