Dating artifacts (Young earth vs old earth)

RoseBud, I think I know what you meant. You'd be surprised at how precise jargon in a field can be.Just FYI, man-made diamonds are not EXACTLY the same as those produced in nature. The main difference is that there are no inclusions (impurities) in the lab-grown diamonds. However, as far as crystalline structure, I think, that they are the same (although, if it is true that they are not as strong, then maybe there is even some difference in that).My dad IS a GIA certified gemologist (not a geologist). I'm a biscuit cook. My dad knows a lot about gem stones...I know a lot about flour dust and the phrase "how long!?!." .You probably meant, that it was not a material that only LOOKS like diamond.The correct term (I think)is SYNTHETIC (meaning man-made, not fake). But there is some overlap, of course. Words can have different meanings depending upon the field people are in and even more of a difference when among laypeople (like you and me), and this is a source of confusion. "Synthetic" and "artificial" can also simply mean "fake," which is how you take the word and how you used it.To be safe, use the word "lab-grown" for these diamonds and say they are not "fake" or "simulated." BTW, Jewelery stores DO sell fake diamonds ~ Zirconium (I think) and Moissanite (or something like that) are two examples of simulated diamond materials ~ they are also lab-grown crystals.Roxrkool (rocks are cool?) is a geologist, I think.So, Roxrkool, how old are diamonds and how do geologists arrive at this age? If you don't mind my asking.
