Raw Boulder Opal — Blue-Green Flash, Australian

This raw Boulder Opal displays vivid iridescent blues and greens that shift naturally with the light, its soft milky flashes making it a genuinely striking display specimen. At 90mm long and 155g, it keeps its natural, unpolished form, showing the opal exactly as it emerged from the Queensland ground.

So what makes this raw form worth choosing over a cut stone? A raw specimen preserves the opal's natural connection to its host rock, every curve and colour flash formed by nature over millions of years, telling its own geological story rather than being shaped away from it. Boulder opal is often associated with inspiration and creativity, popular among those seeking personal growth and self-expression.

About this specimen

Because this is a natural, raw formation, its exact shape and pattern of colour are entirely unique to this piece, so you will never find another exactly like it. Boulder opal is durable thanks to its ironstone backing, which supports the delicate opal layer far better than opal alone, making a raw specimen like this genuinely practical to handle and display compared to a solid opal without any matrix support.

• Stone: natural raw Australian Boulder Opal

• Size: 90 x 44 x 28mm, 155g (0.34 lb)

Displaying your Opal

A shelf or desk out of strong direct sun helps protect the colour play over time. Dust with a soft, dry cloth, and avoid harsh chemicals or sudden temperature changes, treating it with the same care you would give any one-of-a-kind natural specimen.
