I know this isn't a "Glow" question but I can't find the answer anywhere on Google and it's too late to go to a library now. Maybe I didn't look hard enough or maybe it was right under my nose and my brain skipped it idk I need help. what is the purest metal on earth? OR what type of metal is the metal used for the 5 Chinese elements? a bit of background: I would like to make myself a necklace with only genuine raw crystals, pure metal, and genuine unpolished petrified wood but I don't know what metal is the best to use. also if anyone has any legit knowledge of the Chinese elements what are the best crystals to represent fire, water, and earth from an ancient Chinese point of view? I really need help I want to make this so badly! I really want an authentic as possible necklace made by myself.
