📜 Key facts

Age	Formed in Oligocene–Miocene volcanic rocks (roughly 30–20 million years old)
Origin & sources	Wollo (Welo) Province, Ethiopia, commercially mined since 2008.
Composition	Precious opal from volcanic rocks. Much Welo opal is hydrophane: it soaks up water, temporarily turning clear or losing its colour, and returns to normal when it dries. Don't soak it, oil it or use it in elixirs. 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.
