A sharp specimen with a leaning tower of intergrown crystals perched one atop another and leaning out over the sphalerite matrix to present out to you that 3-cm cuboctohedron floating at the right. The rest of the cluster shows more classic Naica "stairstepping" and complexly bevelled crystals closer to the cubic habit, but with lots of outgrowths. Like many from this pocket, even the back is munitely crystallized or rehealed after an old break, making this complete all around and entirely translucent.
