Also, this may seem like a weird question but, although it is the same chemical composition, is it technically a "fake" according to gemstone standards or is it considered as genuine as those from the mines? Do you know whether the determination of whether it's genuine is based on origin or composition?

If you were to go to Kay's or something, most likely you'd buy a mined diamond. But there are several companies out there who sell lab-made diamonds, not only as loose stones but also set in gold and platinum.
As for the chemical composition...All a diamond is is carbon. What makes it so different (and valuable) is the way that the carbon atoms bond together to form a crystal structure. If it has that structure, its a "real" diamond, no matter whether is was made in a lab or made in a mountainside. Determination of being a "genuine" diamond is only based on having the correct chemical composition and the correct crystal structure. For example, graphite (pencil leads) are also carbon, the atoms bond in a completely different way, giving you different properties. Testing can be done to determine how the carbon atoms are bonded and chemical composition.
Below is a great article from salon.com if you're interested in learning more about the lab-made diamond industry.
