I don't have any qualification with crystals , but I would -
check your local crystal shops / alternative shops -
look in the back of alternative magazines -
do a search on Google -
It will depend I think on how you want to use crystals - is there anything in the back of the embody magazine ?
Phone up crystal therapists and ask where they trained ..... Not sure if that is any help, as you didn't say what you had already tried.
