Hi,

    with regards to your post referring to diamonds completely
    disappearing after being baked in PMC. 

    I have limited knowledge of chemistry but have read a little on this
    subject. 

    You may be interested to know that chemists and jewellers have
    recorded this happening since 1690. 

    In 1796 the mystery was solved by a British scientist, Smithson
    Tennant. It turns out that diamonds (a rare, transparent form of
    carbon) when burned with a free supply of oxygen will be completely
    converted into carbon dioxide leaving no trace of the diamond.... 

    conclusion: don't bake your stones!
