📜 Key facts

Age	Varies
Origin & sources	Tanzania (Haneti), Australia and Poland.
Composition	Green common opal. 'Prase opal' is coloured by nickel, as in chrysoprase. 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.
