Hello Doug,

    I'm sure you can find both of these items quite readily in the U.S.
    although true Oxblood Coral is getting absurd prices these days here
    in Canada. 

    I would be interested to learn if the client knows the problems
    associated with natural yellow sapphire.  The green is considerably
    more stable than the yellow. The stones that have a strong green
    will retain their yellow quite well but if the green is very pale
    the yellow fades and washes out much quicker. The resultant stone is
    not attractive. Fading can be prevented by avoiding daylight but it
    will fade faster than a Kunzite. 

    In my opinion Natural yellow Sapphires, Brown Mexican Topaz,
    Kunzites and any other 'faders' should NEVER be used in jewellery as
    these are collector stones that need to be stored properly to retain
    their 'natural' beauty. 

Tony.
