    Hi Everyone out there ! I am not an expert on Gemstones, but would
    like to add somethings here which I find missing. Sorry Gerry but I
    seem to differ with your opinion in this case, you seem to be making
    it difficult for Sharron  her friend to make up their minds in
    favor of a stone instead of helping them take an objective point of
    view. To a greater extent I would agree with Daniel that heat
    treatment or not ( a natural ), a stone should primarily appeal to
    the soul of the intending buyer( and of course suit the budget too
    ).If a buyer thinks that any person, institute or Lab is going to
    back up the responsibility of buying a stone 100%, it
    issomething that is not going to take place. But 99.99% of the
    times the opinion/s expressed bya reputed Gemmological
    institute is correct technically (except that of the Origin of the
    stone ). Generally heat treatment makes a difference of 10 to 20% in
    the price factor but ultimately is is the total appeal of the stone.
    Firstly and foremostly we have to understand what makes a dealer go
    in the favor of heating a stone ? What is the process ? What changes
    the stone undergoes before and after heating ? etc., etc. As I
    understand, Gemstones are formed when there are favorable conditions
    of different minerals, temperature, pressure etc and gemstones are
    formed. In some of the cases and the stones are somewhat "raw " when
    they are mined. So depending on each every individual stone a
    decision is taken whether it requires heat treatment to bake it
    fully ( and most of the times results in a better stone color
    &claritywise. There is no guarantee of any result and it
    is all based on decision taking based on an individuals experience
    and expertise.In heat treatment the stone is heated to nearly its
    melting stage where a reallignment of its consitutents takes place
    and cooled in a more rapid time frame ( than it was heated ) to
    freeze the beneficial changes. Diffusion is a process wherein a
    coating of color( the same minerals that impart distinctive color to
    a stone )is made superficially on a faceted stone and which
    needless to saywears outwith use time ( specially
    on the edges ).It is therefore an unaccepted treatment in the
    industry. A few more pages can be written to describe all the
    treatments done and their acceptability and non acceptability so I
    would not take more time & space here. (You may read a
    book onthe treatments etc of gemstones to get more
    professional & updated information ). In my opinion buying
    a stone is similar to buying a car or a house or making any other
    investment wherein you take an INFORMED decision and you stay
    with it and where NO ONE guarantees you the final result. You take a
    calculated risk and surely your life is not atstake. The only
    important thing is whether you can make do with the loss of that
    amount ( in the worst come worst scenario ). It indeed helps if
    you are buying a stone in your own country for the reasons Gerry
    states. From sharron's mail the thing I am able to make out that she
    has a liking for Sri Lankan material whichhas more crystal to
    it (generally rather than as a rule )as compared to Thai material. I
    have been associated with the gemstone industry for a decade now,
    & If you were to describe the quality and carat wt. of the stone
    you are looking for maybe I couldhelp you with a few
    tips on the pricing aspect, and maybe give a referral of a suitable
    vendor ( of that quality ). I wish you all the best in your endeavor
    to buy a Sapphire.
