Lab grown diamonds can be more sustainable, based on how they are produced. Firstly, they do not require mining which means there is no need for deforestation, earth moving or any mining equipment to produce them. However, the amount of energy required is significant so only some lab diamonds can be truly considered sustainable – those who use renewable resources for their energy. Some producers are carbon neutral or even carbon positive in their production, meaning they produce the same amount or more energy as they use.
