  • St. Lawrence Co.
    New York, USA
  • This is a cool specimen. It is tremolite! The variety called "hexagonite" that is seen in certain parts of the Grenville in New York State. It has a unique purple colour, very unusual for tremolite. This crystal has been replaced carefully onto the finer-grained tremolite matrix from whence it came and looks great. It is at least singly terminated but I am not sure about the upper termination. It appears to be not a termination while the lower termination is a good termination. Sawn base enables this specimen to sit perfectly for display. NY classic! s
