    It occurs to me that the pharmaceutical industry has to be very
    careful with terminology. Are there any examples that would apply to
    gemstones? For example, do they use the word "synthetic" to describe
    a man-made hormone that is chemically identical to a naturally
    occurring hormone? What about a drug that performs the same function
    of some natural substance but is chemically different?--is it a
    synthetic, or is there another term used? 

    The lines still get blurred with drugs that don't mimic any known
    bodily process. 

    I figure that a synthetic gem is a man-made copy, chemically and
    physically identical to the original. A simulant only looks the
    same, so a cubic zirconium is a diamond simulant. 

    The blurring of the lines: YAG is man-made but marketed as a new
    variety of gemstone, not as a substitute for any natural stone. I
    consider it a synthetic gemstone--but who am I to say?
