Description

The universe has 13.8 billion years of history. Some of it fits in your hand. Twelve specimens spanning Earth’s 4.56-billion-year story, one per geological era. From a 4.4-billion-year-old zircon (the oldest mineral on Earth) to a Roman volcanic glass and a modern fulgurite. Each specimen arrives with a timeline card and geological context. Start at the beginning; hold time in your hands.

This specimen originates from Global, 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

Each specimen in this collection was individually selected for quality and scientific interest. The combination has been chosen to illustrate a specific geological or mineralogical theme, with each piece complementing the others.

Locality

Geological Timeline Collection — 12 Specimens — Educational Edition from Global. This locality is known for producing specimens of exceptional quality.

Collector Notes
