Large flat schist matrix covered by white Natrolite, numerous black Neptunite crystals, and small brown crystals of the rare mineral Joaquinite. This is a newly prepared from material that was mined years ago. Neptunite from this mine is considered the worlds best and this one has lots of good crystals. This mine is long closed and specimens are getting harder to find, especially larger specimens such as this.
