Found in the late 1800s, these were old classics even before the mines were shut down and closed. GEMMY, brilliantly purple CRYSTALS of this tremolite varietal abound in massive matrix of the same. This is a large, rich piece. You could certainly break it up into many smaller specimens with ease, each with some gemmy crystals in it. This is typical of the higher quality level I see every now and then, preserved in old collections.
