    Firstly, as I have noted on this forum several times in the past and
    am willing to do so again especially since this is a query from
    Noel:  for those interested in stone and/or lapidary an essential
    book is "Gem Cutting" by John Sinkankas.  It's basic reading.

    Now for Noel specifically,  as you mention there are solutions with
    RI's that match or are close to RI's of specific materials;  i.e.,
    opal and glycerin.  Sometimes the answer is to polish a window into
    the rough. 

    One caveat, don't divide material into faceting grade and caboshon
    grade. Remember inclusions are not flaws; they are nature's
    fingerprints. The R.I. of aquamarine, one of the beryls is 1.56-1.6
    according to John Sinkankas. I don't have time to research the name
    of a solution that would be appropriate;  I have to get back to my
    rocks.
