This is the richest specimen of acanthite in the lot, with huge crystals overarching from the matrix like the crown of a tree. It is comprised of more than ten octahedral crystals, all of them pointing upward and out, with much more 3-dimensionality in person. At least two of these crystals reach the astounding size of 3 cm in length! They also possess halfway decent luster, especially for this find. Minor associated white Baryte crystals really complete the piece by providing accent. This one is much better in person.
