    Hi all: We need some help from the 'stone people' for a beginner (my
    daughter) who is just beginning to carve stones and who is asking me
    questions I can't answer. She is using a flexible shaft, diamond
    powder, and some premixed diamond powders of various grits. So here
    are the questions: 

    1. When polishing a stone like a small, rough emerald, with a
    flexible shaft, in what order should the grits be used and what kind
    of buffs? How would it differ from polishing softer stones? 

    2. How do you determine when to move on from one grit to the next
    level and how long should it take (all day?) for the final polish. 

    3. What is the best book for beginners who are essentially self
    taught (she has an MFA in printmaking, but this is her first attempt
    at stone carving--and she loves it). 

    4. Any other help or advice would be greatly appreciated.  I will
    send it all on to her, and in the process learn something myself.
