Turritella Agate Gemstone Beads

Our turritella agate beads are a beautiful blend of subtle color and crazy pattern. The understated black, brown, and cream tones are a lovely compliment to the wild, whirling spiral pattern created by the fossilized shells.

The gorgeous whorls and spirals in Turritella agate are actually the fossilized shells of freshwater snails (called Goniobasis or Elimia)! This fascinating gemstone comes from the Green River Formation in Wyoming, Utah, and Colorado and was created from layers of material that were deposited in a series of ancient lakes approximately 40-50 million years ago!
