The History of Pearls: Ancient Seas to Cultured Pearls | Murun Pearls

Long before the art of diamond cutting existed, pearls had already captured human imagination. From the moment they were found, these organic gems carried their own shape and shine — no faceting required, no polishing to reveal a hidden brilliance. A pearl simply needed to be cleaned, drilled and set.

That immediacy is part of why pearls have accompanied human history since its earliest chapters. Yet the story of the pearl is about far more than beauty. Behind its soft glow lie tales of royal courts, cross-continental trade, divers who risked their lives beneath the waves, fierce competition over natural resources, and innovations that would eventually transform the entire jewellery industry.

This is the history of pearls — a journey from ancient waters to the modern boutique.

A Journey Through Pearl History at a Glance

The Origins: A Gem Born of Water

No single date marks the moment pearls were "discovered." They were most likely found by accident, as coastal communities gathered molluscs for food or harvested their shells.

Unlike most gemstones, a pearl's beauty needs no lapidary skill to reveal it. Yet its appearance in nature is entirely unpredictable — a person might open hundreds of shells without finding a single gem-quality pearl. That scarcity gradually gave pearls economic, social and even spiritual value.

Across many cultures, their round form and soft glow became linked to the moon, to water, to purity, wisdom or protection. The symbolism was never identical from one civilisation to the next, but one idea repeated again and again: a pearl was always considered more than simply a pretty object.

Persia, India and Sri Lanka: Cradles of the Ancient Pearl Trade

For centuries, the waters of the Persian Gulf and the Gulf of Mannar — between southern India and Sri Lanka — were among the most important sources of natural pearls in the ancient world. Coastal communities harvested mother-of-pearl shell alongside the occasional pearl that formed within.

In ancient Persia and India, pearls appeared in royal dress, ceremonial ornaments, diplomatic gifts and the private collections of rulers. Their value came not only from appearance, but from the sheer difficulty of finding a pearl that was large, attractive and reasonably symmetrical.

These pearl-producing regions also sat along vital trade routes. As goods, people and ideas moved from port to port, pearls travelled with them — carrying their lustre far beyond the waters where they were found.

When Trade Routes Connected East and West

Pearls had long been treasured in East Asia. According to the Gemological Institute of America (GIA), the earliest known written reference to pearls appears in Chinese records dating to around 2206 BC, placing pearls among humanity's earliest documented treasures. Communities across China, Japan and the Pacific islands also gathered natural pearls from both freshwater and marine molluscs.

Meanwhile, the expansion of the Hellenistic world following Alexander the Great's conquests strengthened ties between the Mediterranean, Persia, Egypt and India. No single figure "introduced" pearls to the world, but this widening web of politics and trade helped the gem travel further than ever before.

Later, the overland network known as the Silk Road connected demand in China with pearls sourced from India and the Gulf. Even in its earliest chapters, pearl history was a global story — a small, precious object capable of extraordinarily long journeys.

Rome: Pearls as the Language of Luxury

In the Roman world, pearls became a highly visible marker of wealth. They adorned ears, necks, garments and accessories alike. Museums such as the British Museum and the Metropolitan Museum of Art hold Roman gold earrings set with pearls, some dating to around the first and second centuries AD — a testament to how established the taste for pearl jewellery had already become.

Perfectly round pearls were rare, and irregular shapes were common and widely accepted. At a time when every pearl had to be found in nature, simply owning several that could be matched together already signalled access to trade and considerable wealth.

Roman elites were also known for embracing dramatic display. Pearls became more than personal adornment — they were a subtle, and sometimes not so subtle, way of communicating status to everyone else.

Byzantium, the Islamic World and the Pearling Traditions of the Gulf

As the centre of Roman power shifted and transformed, the appetite for pearls never faded. In Byzantium, pearls were combined with gold and coloured gemstones in jewellery and ceremonial objects. At the same time, trade networks across the Islamic world connected the Gulf, Persia, India, North Africa and the Mediterranean.

Bahrain and its surrounding waters became one of the most significant centres in this story. UNESCO's inscription of Bahrain's Pearling Path recognises how the pearling trade shaped the region's economy and cultural identity from around the second century through to the 1930s. Merchant settlements, storehouses, harbours, boats and oyster beds together formed an entire economic ecosystem built around the pearl.

Yet the luxury enjoyed on land rested on extraordinarily demanding work at sea. Long before modern diving equipment existed, pearl divers descended repeatedly on a single breath, working with nets and facing the risk of injury, exhaustion and unpredictable conditions. Only a small fraction of the shells they gathered ever produced a pearl of real value.

Scholars such as the Persian polymath Al-Biruni, writing in the tenth and eleventh centuries, also documented pearls and the practice of pearl diving — a reminder that the history of pearls is not only a history of fashion, but equally one of trade, science and maritime knowledge.

Medieval and Renaissance Europe: Pearls as a Portrait of Power

Throughout the Middle Ages, pearls moved across Europe through trade, diplomacy and conflict. Because they remained rare and costly, their use was concentrated largely among royalty, the nobility and religious institutions.

During the Renaissance, royal portraiture revealed just how effectively jewellery could serve as political communication. Queen Elizabeth I of England, for example, was frequently portrayed with pearls woven through her hair, draped at her neck and stitched into her gowns. Pearls reinforced an image of purity and majesty, while their sheer abundance in these portraits also announced wealth and power.

In Russia, pearls adorned crowns, brooches, earrings and necklaces within the imperial collections. Across Europe's other centres of power, the gem became part of a shared visual language of monarchy. In short, pearls were never simply worn — they were used to construct an image.

The Age of Exploration: New Sources, Hidden Costs

When European voyages reached the Americas at the close of the fifteenth century, natural pearl sources in what is now Venezuela and Panama drew intense interest. Christopher Columbus recorded encounters with local communities who had already been wearing and collecting pearls long before Europeans arrived.

Growing demand from European markets soon drove large-scale extraction. Behind the wealth flowing back to Europe lay a darker chapter of history: colonisation, forced labour, and severe pressure on wild mollusc populations.

Many natural pearl beds declined sharply as a result of overharvesting. To read pearl history honestly means looking beyond the jewels that reached royal courts, to also consider who gathered them from the sea — and what that extraction cost the environment.

The 19th Century: Pearls Beyond the Royal Court

By the early 1800s, pearls were appearing more frequently in European jewellery design. Tiny seed pearls were arranged into motifs of flowers, leaves and ribbons. During the Victorian era, pearl strands, cameos and sentimental brooches became central to fashionable dress among the well-to-do.

New sources also drew attention during this period. Pearls were found in Australian waters and in rivers across North America. Softly coloured freshwater pearls were used in brooches and necklaces, while freshwater mollusc shell became the raw material for a booming mother-of-pearl button industry.

This market expansion carried its own consequences. Intensive harvesting and the shell trade placed pressure on numerous mollusc populations. When plastic began to replace shell buttons in the twentieth century, one industry declined — but a far greater transformation was already underway, this time from Japan.

The Cultured Pearl Revolution

Efforts to help molluscs form pearls had actually existed in China centuries earlier, largely in the form of blister pearls that grew attached to the inside of a shell. However, the breakthrough that would reshape the global jewellery market took place in Japan.

After years of experimentation, Kokichi Mikimoto successfully produced his first cultured pearls in 1893, followed by fully round cultured pearls in 1905, according to the Gemological Institute of America. Japanese cultured pearls began to carry real commercial significance during the 1920s.

Their arrival was not without controversy. Some traders initially viewed cultured pearls as a threat to the value of natural ones. In truth, a cultured pearl is still formed entirely by a living mollusc and remains a genuine pearl — the difference lies only in how the growth process begins.

Culturing made supply far more predictable, even though every harvest still depends on a living organism and its environment. Gradually, pearls became accessible beyond royalty and the wealthiest collectors. More people could now own pearl jewellery, choosing from a far wider range of sizes, colours and price points.

From Japan to Indonesia: Pearls Become a Global Industry

After the Second World War, Japan's pearl industry recovered and expanded. Cultured-pearl knowledge and technology gradually spread and adapted to different species and environments around the world.

French Polynesia became known for dark Tahitian pearls, Australia for white South Sea pearls, while the Philippines and Indonesia developed South Sea pearls ranging from white to golden hues. China, meanwhile, grew into a major centre for freshwater cultured pearls.

Indonesia holds a distinctive place in this modern chapter. Its waters are home to Pinctada maxima, the mollusc responsible for South Sea pearls, which can grow to a considerable size. GIA has documented pearl cultivation on Lombok, including bead-nucleated cultured pearls as well as non-bead cultured pearls commonly traded as keshi.

Indonesia's place in pearl history, then, is far from a footnote. It forms part of a broader shift of pearl production toward the Indo-Pacific — a region that today plays a major role in the global pearl market.

What the History of Pearls Teaches Us

This long history reveals that a pearl's value has always been built from more than its lustre.

Scarcity Shaped Power

When the entire supply depended on chance discoveries in nature, pearls could only be gathered in meaningful quantity by rulers and the wealthy. Rarity, more than anything else, determined who could wear them.

Beauty Always Has a Journey

A single pearl might travel from the seabed to a diver's hands, then to a trader, a craftsman, a royal court, and finally down through generations. Along that journey lies human labour and environmental impact that deserve to be remembered, not overlooked.

Innovation Changed Access, Not Wonder

Culturing allowed far more people to wear pearls, yet the mollusc remains the one that builds every layer. Humans can begin and tend the process; nature still determines the result.

From Persia, India, China and Rome to Japan and Indonesia, the history of pearls is really a story about humanity's relationship with water. Its meaning has shifted across the ages — once an offering, a currency, a symbol of monarchy, a colonial commodity, and today, a deeply personal piece of jewellery worn to mark life's most meaningful moments.

What has never changed is its pull on us. Every pearl still carries a shape, a surface and a lustre built slowly by a living creature — a trace of nature that has captivated people for thousands of years.

At Murun Pearls, we see every piece of jewellery as a new chapter in that long story: rooted in history, yet designed to be worn and cherished today.
