138.58ct Gray Opal Rough Seam

Rough Lightning Ridge Opal

Sourced from the world-famous opal fields of Lightning Ridge, NSW, our rough opal is completely natural and untreated. Each piece is hand-selected for its potential, character, and unique play of colour.

Whether you are a cutter, collector, jeweller, or investor, rough opal offers the opportunity to uncover something truly one-of-a-kind. No two stones are ever the same — every piece carries its own pattern, colour distribution, and formation shaped by millions of years underground.

All rough is sold in its natural state. Some pieces may display visible colour bars, seams, or promising faces, while others require further exploration to reveal their full potential. We do our best to photograph each piece accurately under natural lighting, however opal can shift in appearance depending on light source and viewing angle.

Authenticity & Presentation

Each opal is entirely natural and one of a kind. Photography is conducted under professional lighting to capture the stone’s fire and colour as accurately as possible. Due to lighting environments, movement and individual screen settings, subtle variations may appear in person.

 Opal is a living gemstone — its appearance evolves with angle, light source and intensity. This dynamic nature is part of its beauty and value.
