    the draker green the more $$$ you get.
    chemical formula: Be3Al2SiO6
    SG: 2.6 - 2.8
    Hardness: 7.5-8 (about the same as quartz)

    Mohs Number Mineral Examples
    1 Talc
    2 Gypsum
    2.5 Fingernail
    3 Calcite Copper Penny
    3.5 Adamite
    4 Fluorite
    4.5 Steel Nail
    5 Apatite

    try looking at it's hardness by scratching it with i.e quartz.
    Geologists are gneiss, tuff, and a little wacke.

    Serpentine,, we have tons of it here in Harmony NJ
    What is thrilling to me about finding an old coin is that you are the next person to touch it after the person who lost it. It is an unexplainable fasination.
