Diamonds are among the most valuable jewels on our planet. They are formed under extreme conditions deep below the Earth’s surface through a great deal of heat and pressure. Historically, the diamond industry has caused many problems for the environment. The mines where diamonds come from can be very unpleasant for workers, and the process of mining diamonds can do a lot of damage to the surroundings. This is why many people are now looking to lab-grown diamonds as an alternative.
鑽石是地球上最有價值的寶石之一。它們是在地球表面之下的深處，處於極端條件並經歷大量的熱能和壓力形成的。在歷史上，鑽石產業對環境造成了許多問題。採鑽的礦井對工人來說可能極為不適，開採鑽石的過程也會對周遭環境造成很大的破壞。這就是為什麼許多人現在視實驗室培育鑽石為替代品。
