Few gemstones carry as much conflicting symbolism as opal. For thousands of years across multiple civilisations, opal was considered one of the most fortunate stones a person could wear — associated with hope, love, purity, foresight, and protection. Then, in the space of about fifty years during the 19th century, its reputation inverted. Suddenly opal was unlucky, dangerous, a stone that brought misfortune to its wearer.
The story of how that shift happened — and whether there's any truth to it — is one of the more fascinating case studies in how superstition spreads. It involves a Scottish novelist, a panicking diamond cartel, Queen Victoria, and a 19th-century gift book that seems to contradict everything you've heard about opal's "bad luck" history.
This guide walks through what opal has actually meant across cultures and centuries, where the bad luck myth came from and why it's wrong, and what opal symbolises today for Australian buyers specifically. It's the historical and cultural side of opal, distinct from the crystal healing and chakra associations we cover in our opal healing properties guide.
What Does Opal Mean? The Short Answer
Across the longest span of recorded history, opal has symbolised:
Hope — the single most consistent association across Roman, medieval European, and Arabic traditions.
Purity and truthfulness — Roman writers described opal as embodying the virtues of all gemstones combined.
Creativity and inspiration — the shifting colours of play-of-colour were seen as reflecting imagination itself.
Protection and foresight — medieval Europeans wore opal as a talisman against evil and as an aid to prophetic dreams.
Emotional depth and transformation — the way opal's colours shift with angle and light was interpreted as mirroring inner change.
In Australia specifically, opal has become the national gemstone (officially designated in 1993) and carries deep cultural significance connecting to Aboriginal Dreamtime traditions and the country's geological identity.
The "bad luck" association, which many people know as opal's primary meaning, is significantly younger — roughly 200 years old — and has almost no foundation in opal's actual historical symbolism. We'll get to that.
Where the Word "Opal" Comes From
The etymology of opal tracks through three ancient languages, each adding a layer of meaning:
Sanskrit upala — meaning "precious stone" or simply "stone." The oldest recorded root, appearing in Indian texts that predate most Western literature on gemstones.
Greek opallios — derived from the Sanskrit, meaning "to see a change in colour." The Greeks were among the first to recognise what we now call play-of-colour as the defining characteristic.
Latin opalus — the Roman form, which became the direct source of the modern English word. Pliny the Elder, the Roman natural historian, described opal in his Natural History (circa 77 CE) as possessing the "gentle fire of the ruby, the brilliant purple of the amethyst, the sea-green of the emerald, all glittering together in an incredible mixture of light."
That description — opal as a stone that contains all other stones — is the foundation of nearly every positive symbolic association that followed. If opal holds the fire of ruby, the calm of emerald, the wisdom of sapphire, it inherits some of what those stones represent.
Opal in Ancient Rome
The Romans didn't invent opal symbolism, but they documented it most thoroughly. Pliny's description established opal as the "gem of gems" — a stone that combined the virtues of every other precious material. Roman wearers associated opal with:
Hope and purity. The clearest consistent Roman meaning. Opal was given as a gift to signal optimism and emotional cleanliness.
Powerful talismanic properties. Wearing opal was believed to grant the protective qualities of all the stones whose colours appeared in its play — red fire for courage, blue for truth, green for healing.
Connection to divine fortune. Roman legend sometimes traced opal to the tears of Zeus — formed when the king of the gods wept tears of joy after defeating the Titans. Other versions traced opal to lightning strikes falling to earth during storms.
The famous Roman senator Nonius reportedly owned an opal the size of a hazelnut that Mark Antony coveted. When Nonius refused to sell, Antony threatened exile — and Nonius chose exile over surrendering the stone. That degree of attachment speaks to how seriously the Romans valued opal, both materially and symbolically.
Opal in Medieval Europe
Medieval European symbolism built on Roman foundations but added specifically Christian and mystical dimensions:
The "Opthalmius" legend. A persistent medieval belief held that wrapping an opal in a fresh bay leaf granted the wearer invisibility. This earned opal the informal title of "patron stone of thieves, robbers, and spies" — a reputation worth knowing about even if nobody takes it seriously today.
Protection against evil. Opal was widely worn as a talisman to ward off the evil eye, disease, and misfortune. This is ironic given what came later.
Associations with prophetic vision. Medieval writers connected opal's shifting colours to dreams, intuition, and the ability to perceive hidden truths. This is the historical root of the modern "creativity and imagination" associations that persist in crystal healing contexts.
Symbols of faithfulness. Given as tokens between lovers and in betrothal gifts as signs of loyalty and devotion.
Throughout the medieval period and well into the Renaissance, there is essentially no evidence of opal being considered unlucky. That idea is a 19th-century invention.
For over a thousand years before the 19th century, opal was considered one of the most fortunate stones a person could own.
Opal in Aboriginal Australian Tradition
Aboriginal Australians have their own ancient relationship with opal that predates any European contact. In Dreamtime stories from several nations, opal is connected to the creation of the land itself.
One Dreamtime story holds that the Creator came down to Earth on a rainbow, bringing messages of peace to all people. Where the Creator's feet touched the ground, the stones beneath came to life and sparkled with all the colours of the rainbow — and that is how opal was born. The colours within the stone are the Creator's footprint.
Another tradition describes opal as the resting place of a great rainbow serpent — a being that travelled across the Australian continent shaping the landscape, its colours preserved in the stones found along its path.
These stories matter because they connect opal to place in a way that European traditions don't. For the oldest continuously living culture on Earth, opal isn't a generic gemstone that happens to be found in Australia — it's specifically, essentially, an Australian stone with meaning embedded in the land itself.
The "Bad Luck" Myth: Where It Actually Came From
If you know one thing about opal symbolism, it's probably the superstition that opals bring bad luck. Here's where that idea actually originated — and the scholarly caveats most articles miss.
Sir Walter Scott and Anne of Geierstein
In 1829, the Scottish novelist Sir Walter Scott — the most widely read author in the English-speaking world at the time — published a gothic novel called Anne of Geierstein. The plot involves a Baroness named Hermione who wears an enchanted opal in her hair. The opal's colours shift with her moods — bright when she's happy, fiery when she's angry.
In a pivotal scene, drops of holy water fall on the opal. The stone "shot out a brilliant spark like a falling star, and became the instant afterwards lightless and colorless as a common pebble." Hermione collapses, and by the next morning, all that remains of her is "a small heap of ashes."
Nothing in the novel actually presents the opal itself as the cause of Hermione's death — the story is about an enchanted stone tied to the life-force of a specific supernatural character. But Victorian readers took a different message. Sales of opal in Europe reportedly dropped 50% within months of publication, and remained depressed for roughly twenty years afterward.
The Scholarly Caveat Nobody Mentions
Here's the interesting part most competitor articles miss: there's actual historical evidence that the Scott-caused opal panic may not have been as sudden or dramatic as the standard story suggests.
The Wikipedia entry on Anne of Geierstein — and the original scholarly sources it cites — notes several complicating facts. A popular gift book published in the 1840s was actually titled The Opal, which would be strange if the stone were universally considered unlucky at that point. In 1875, Queen Victoria's private secretary Sir Henry Ponsonby wrote to the journal Notes and Queries asking about the origin of the superstition — and the scholarly responses he received didn't mention Scott's novel at all. They referenced other sources entirely.
The conclusion historians have drawn is that the superstition likely consolidated gradually over the middle of the 19th century rather than emerging fully formed in 1829. Scott's novel probably contributed, but the broader shift in opal's reputation seems to have required multiple cultural forces to fully establish itself.
The Diamond Industry Theory
One of those forces, according to multiple Australian opal industry sources, was deliberate market manipulation by diamond dealers. At the turn of the 20th century, Australian opal was flooding into European and American markets in unprecedented quantities. The finest black opals were being compared favourably to diamonds as luxury gemstones.
The dominant diamond cartel of the era — De Beers, which by the 1880s controlled roughly 90% of global diamond production — is alleged to have actively reinforced opal's bad luck reputation through word-of-mouth marketing, social gossip, and media placement. The goal was straightforward: protect diamond's position as the premier luxury gemstone by undermining its fastest-growing competitor.
Whether this was coordinated or organic is difficult to prove definitively more than a century later. But the timing — opal superstition intensifying precisely as Australian opal threatened diamond's market dominance — is at minimum a coincidence worth noting.
Queen Victoria's Response
Not everyone bought into the superstition. Queen Victoria herself is often cited as a vocal opal defender. She wore opals publicly, gave opals as wedding gifts to each of her five daughters, and dismissed the bad luck associations as nonsense. Given Victoria's enormous cultural influence across the British Empire, her visible support likely kept opal from becoming truly pariah-level unfashionable.
More recently, the Australian actress Cate Blanchett wore spectacular Australian opal earrings to the 2014 Academy Awards — where she won Best Actress. Whatever one thinks of luck as a concept, that's not the outcome you'd expect if the superstition had genuine predictive power.
Meaning by Opal Colour
Different varieties of opal have accumulated distinct symbolic associations over time, related to their visual character:
Black opal — strength, protection, and grounding. The dark body tone and dramatic play-of-colour have led to associations with inner power, personal boundaries, and the courage to face difficult emotions. Historically the rarest variety, black opal has carried premium symbolic weight for collectors and wearers. See our black opal guide for more on this variety.
White opal — hope, purity, and new beginnings. The light body tone and softer colour play align with the classical Roman associations of opal with optimism and emotional cleanliness. Historically the most accessible opal variety. Read about white opal's character and appeal.
Boulder opal — connection to earth and place. The natural ironstone backing embeds the opal within its host rock, symbolically rooting the gem to the physical world. Strongly associated with Queensland heritage and Australian landscape. See our boulder opal guide.
Crystal opal — clarity of vision and insight. The transparent to semi-transparent body allows colour play to appear suspended within the stone, leading to associations with mental clarity, prophetic insight, and clear communication.
Fire opal — passion, energy, and transformation. The warm orange-to-red body colour connects to associations with desire, drive, and bold action. More prevalent in Mexican and Ethiopian traditions than Australian ones.
Opal as the October Birthstone
Opal has been designated the traditional birthstone for October for centuries, with origins that may trace back to Biblical and classical birthstone traditions. In 1912, the American National Association of Jewelers published a modernised birthstone list, and opal briefly lost its October position to tourmaline — which has since returned opal to shared October status.
For people born in October, opal carries additional meaning as a personal birthstone. It's also the traditional gemstone for 14th and 24th wedding anniversaries. For more on opal's role as a birthstone and gift stone, see our October birthstone guide and our 24th anniversary opal guide.
Opal in Australian Identity
Australia produces approximately 95% of the world's precious opal. The stone was officially designated Australia's national gemstone in 1993, reflecting its central role in the country's geological and economic identity.
The three primary Australian opal fields — Lightning Ridge in New South Wales (black opal), Coober Pedy in South Australia (white and crystal opal), and the Queensland boulder opal fields — represent not just production sites but distinct cultural regions. Lightning Ridge in particular has developed its own mining town character, where generations of miners have worked the same claims.
For Australian buyers specifically, opal carries a meaning that goes beyond the historical symbolism inherited from Rome or medieval Europe. It represents place, heritage, and a gemstone uniquely tied to the Australian continent in a way no other major precious stone is. That context matters for how Australian buyers relate to opal as a gift, an engagement ring, or a personal piece. See our guide on how opal is formed for the geology that produces this uniquely Australian gem.
Australia produces around 95% of the world's precious opal. The fields of Lightning Ridge, Coober Pedy, and Queensland are central to the stone's cultural meaning for Australian buyers.
Is There Any Truth to the Bad Luck Superstition?
Short answer: no.
The only partial explanation for why opal acquired a bad luck reputation that has any basis in physical reality comes from jewellers who worked with the stone. Opal is relatively soft (5.5 to 6.5 on the Mohs scale) and sensitive to sudden temperature changes. Before modern lapidary techniques were developed, a significant percentage of opals broke during cutting, polishing, or setting. Buyers sometimes took delivery of damaged stones, and jewellers dealing with opal had higher failure rates than those working with harder gemstones.
Some 19th-century cutters refused to work with opal at all — on a "you break it, you buy it" basis. That professional caution, combined with higher-than-average damage rates during setting, probably contributed to opal acquiring a reputation for "fragility" that gradually morphed into "bad luck" in popular imagination.
Modern cutting and setting techniques have largely eliminated this problem. Quality opal set by experienced jewellers in properly designed settings is no more prone to damage than any other softer gemstone. The reputation of fragility — and the superstition that grew from it — persists mainly because it's a memorable story, not because it reflects current reality.
What Opal Means Today
Stripped of superstition and synthesised across traditions, the most durable meanings of opal across history are:
Hope. The single most consistent symbolic association across 2,000 years.
Creativity and imagination. Rooted in the visual character of shifting play-of-colour.
Emotional depth and authenticity. Opal's responsiveness to light and angle has long been interpreted as reflecting the wearer's inner character.
Transformation and change. The stone's visual properties make it a natural symbol for personal growth and evolution.
Uniqueness. No two opals are identical, which has made opal a traditional choice for jewellery that reflects individual identity rather than mass-produced convention.
For contemporary Australian buyers, opal also carries the specific meaning of national heritage and landscape connection — a gemstone that is authentically, identifiably Australian in a way that diamonds, sapphires, and most other precious stones aren't.
