Worldfire - A boulder opal that looks like an entire world caught in intense fire, its red, orange, pink, yellow, blue and green rolling‑flash erupting like molten continents and burning skies wrapped around a tiny planet. Every angle feels like another explosion of colour - a miniature, blazing globe suspended in silver.
This striking Australian Boulder Opal doublet pendant is alive with colour - vivid red, blue, green, orange, pink and yellow rolling across the surface in a dramatic rolling‑flash pattern.

Set in a polished 925 sterling silver pendant, this freeform opal has been shaped and finished to highlight its incredible colour movement.
