This beauty is is a rare find - it is a sphalerite specimen, but it is transparent and green! There are dozens of good crystals, intergrown with dull weathered galena crystals and tiny white quartz crystals (a cluster of which formed the attachment point for this specimen). I have never seen good, transparent sphalerite crystals before, nor green ones, so this one has two unusual features making it special. I would guess that this specimen must be zinc rich, possibly even lacking iron, so it might be nearly pure zinc sulfide.
