When the Campo del Cielo meteorite broke apart over northern Argentina around 2500 BCE, indigenous witnesses described the event as a cosmic fire that changed the world. Four and a half billion years after it formed, a piece of that meteorite sits in the base of each 8.5oz high-clarity glass, clearly visible through the walls, with a Coin of Authenticity seated beneath it as a finishing detail. The set comes in two finishes, Antique Tin or Amber Gold, and holds two tumblers per set.
