Are lab grown diamonds real?

Are lab grown diamonds truly authentic, or are they merely imitations of the real thing? I understand that these diamonds are created in a controlled environment, using advanced technology to replicate the natural processes that occur in the earth. But does that mean they possess the same physical, chemical, and optical properties as natural diamonds? Are they just as durable, sparkly, and valuable? Or are they fundamentally different, and should be viewed as separate entities altogether? I'm eager to hear your thoughts on this topic, as I'm curious about the authenticity and legitimacy of lab grown diamonds in the world of jewelry and finance.
