Shells, pearls and the sea in folklore
For thousands of years, the sea has inspired stories of mystery, danger and discovery. It has provided food, trade and travel, but also represented the unknown—a place where fortunes could be made or lost beyond the horizon.
It is perhaps unsurprising that the treasures carried ashore by the sea came to hold special significance. Shells, pearls and other marine objects were not simply admired for their beauty. They became symbols of protection, pilgrimage, prosperity and transformation, finding their way into jewellery that reflected both the natural world and the stories people told about it.
The first ornaments
Some of the earliest jewellery ever discovered was made from shells.
Archaeological evidence suggests that people were wearing pierced shells as personal ornaments more than 100,000 years ago. Long before metals were worked or gemstones were cut, shells were collected, drilled and strung together, making them among humanity's oldest forms of jewellery.
Their appeal was more than practical. Gathered from the shoreline, shells connected people with the sea and the changing landscape around them. Their natural forms required little alteration, making them objects that were valued for what they already were.
The shell as a symbol of pilgrimage
One of the best-known shells in European history is the scallop shell.
During the Middle Ages, pilgrims travelling to the shrine of Saint James in Santiago de Compostela often returned wearing or carrying a scallop shell as proof that they had completed the journey. Over time, the shell became recognised as a symbol of pilgrimage itself.
The shell also represented guidance and safe travel. Its radiating lines were said to resemble the many routes leading pilgrims towards a single destination, making it an enduring emblem of both physical and spiritual journeys.
Even today, the scallop shell continues to mark pilgrimage routes across Europe.
Pearls and the mystery of the sea
Unlike most gemstones, pearls are created by living creatures rather than mined from the earth.
This unusual origin gave rise to countless stories. Ancient cultures often regarded pearls as gifts from the sea, while others believed they were formed from moonlight, dew or the tears of mythical beings.
Because natural pearls were exceptionally rare, they became associated with wealth and status. Yet they also carried quieter symbolic meanings. Their smooth surface and luminous appearance led many cultures to associate them with purity, wisdom and sincerity.
During the Victorian period, pearls frequently appeared in sentimental jewellery and mourning pieces, where their soft white colour reflected ideas of innocence, remembrance and enduring affection.
Mermaids, sailors and sea charms
The sea has long been fertile ground for folklore.
Stories of mermaids appeared across Europe, sometimes portraying them as benevolent guardians and sometimes as dangerous figures who lured sailors from their course. Whether feared or admired, they represented the unpredictable nature of the sea itself.
Sailors often carried charms believed to encourage safe voyages. Some wore carved shell pendants or coins, while others trusted particular stones or symbols to protect them during long journeys.
The line between folklore and everyday life was often blurred. In an age when survival at sea depended as much on weather as skill, carrying a meaningful object offered reassurance against forces beyond human control.
Cowrie shells and prosperity
Across Africa, Asia and the Pacific, cowrie shells held meanings that extended far beyond ornament.
For centuries they were used as currency, but they also became symbols of fertility, abundance and protection. Their distinctive shape led many cultures to associate them with birth, femininity and new life.
Cowrie shells appeared in jewellery, clothing and ceremonial objects, where they reflected both economic value and spiritual significance.
Their meanings differed across cultures, yet they consistently represented ideas of prosperity and continuity.
The sea as transformation
The sea occupies a unique place in folklore because it is constantly changing.
Tides advance and retreat. Storms reshape coastlines. Objects disappear beneath the water only to return years later, altered by time.
Jewellery inspired by the sea often reflects this sense of transformation. Pearls emerge gradually within oysters. Shells are shaped by currents and waves. Even sea glass begins as something entirely different before becoming softened and renewed.
Perhaps this is why marine motifs continue to resonate. They remind us that change is not always something to fear, but can be part of an object's story.
Throughout history, shells, pearls and other treasures of the sea have represented far more than natural beauty. They have marked journeys, carried prayers, offered protection and symbolised renewal. Whether worn by pilgrims, sailors or collectors, these objects reveal humanity's enduring fascination with the sea and the meanings we continue to find within it.
Many vintage and antique pieces continue to feature shells, pearls and marine motifs today, allowing these centuries-old stories to live on in jewellery that is still worn, collected and cherished.
