Did you know that even though a Diamond is known to be the hardest material mineral known to man, if you hit it with a hammer you would crush it to a powder? This so called hardness relates to its ability to scratch other materials. (PS) Never test a diamond by scratching a glass surface, it will damage the surface of the Diamond. Even a imitation glass diamond will scratch the surface of glass.
