Description

What looks like stone is, on closer inspection, frozen time. The Minoan eruption of Santorini (~1600 BCE) was one of the largest volcanic events in human history — it produced enough pumice to bury its contemporaries. Pumice is volcanic glass so thoroughly vesiculated that it floats on water. Santorini pumice has been found at the bottoms of the Nile and on the shores of Israel — tsunami evidence from the eruption that may have inspired the Atlantis legend.

This specimen originates from Santorini (Thera), Greece, one of the world’s most significant localities for this type of material. Collectors and scientists have drawn from this region for generations, and for good reason: the combination of geological conditions here produces specimens of exceptional quality and clarity.

Every specimen is unique. Photographs approximate the visual experience, but the real thing — its weight, its luster under a raking light, the way it catches the corner of your eye — can only be experienced directly.

Formation

This specimen formed through geological processes operating over timescales that dwarf human history. The specific combination of chemistry, temperature, pressure, and time at this locality produced material of exceptional quality that makes it a valued addition to any serious collection.

Locality

Pumice from Santorini from Santorini (Thera), Greece. This locality is known for producing specimens of exceptional quality.

Collector Notes
