📜 Key facts

Age	Varies
Origin & sources	Andes of Peru (Andean opal), also Oregon (USA).
Composition	Blue-green common opal (Andean or Peruvian blue opal), coloured by copper. Opal is hydrated amorphous silica (SiO₂·nH₂O), Mohs 5.5–6.5.

How it forms

Silica-rich water seeped into cracks, cavities and fossils, then slowly evaporated. Tiny silica spheres settled out. In precious opal they are stacked in a neat, regular grid that diffracts light into play-of-colour. In common opal they are jumbled.
