Linked by archaic translations and mineralogical misunderstandings, the quarterfinals are ending in hexagons with vivid pyromorphite vs writeable graphite.

Hunting vase Francesco Tortorino, Milan, 1550-75 Rock crystal Carved with exceptional skill, the decoration of the central section may refer to Charles V or Philip Il's military deeds. The figure holding a rabbit is possibly a reference to classical Hispania.

I like halite and cuprite as well, but let’s be serious at this point: only quartz offers such a wealth of shapes and colors—and so much enjoyment for amateur mineralogists like myself.

Herkimer diamonds are naturally double-terminated quartz crystals with exceptional clarity, mined primarily in Herkimer County, New York. Double termination is very rare in quartz. Link for more info in ALT!
