You are in violation of most of the FTC regulations and most ethics
based groups’ rules by calling treated, colored diamonds only
"colored diamonds". You MUST always preface these stones with
something like “irradiated colored diamonds” or “synthetically colored
diamonds”. You cannot assume that since you are identifying natural
colored diamonds as natural that this allows you to sell the others as
colored diamonds, since you are not telling the customers how they are
colored and they might not be seeing the natural colored diamonds that
you are selling as well. “Colored diamonds” can ONLY refer to
naturally colored diamonds that have undergone no treatment at all.
