This is a very large and fine example of the "reticulated" form, more like a snowflake in structure. The crystal is complete, with just a few areas of contact on the two ends. You can see from the photos the incredibly complex architectural structure of this crystal. What is less apparent is the wonderful luster, which truly flashes off the faces as you rotate it. This is a big, major specimen, heavy in the hand, of a classic from perhaps the world's greatest mineral locality.
