Magic Forums

Hey guys this is just a question I want to ask since I think it is so cool that you can grow crystals at home and although it won't be perfect for magic that it can have all the properties of regular crystals with it being unfortunately unpredictable. I remember on a google search I saw a forum that was talking about whether or not crystals lab made can have any magical powers and the answer was that yes it can but it will also be unpredictable. I just want to know how to determine the properties of a crystal that was homemade in a lab because I want to experiment with the properties of artificial crystals made in a jar. Thank you.
