Mother of Pearl

Mother of pearl is one of nature’s most luminous gifts with its beautiful lustre and intriguing iridescence. Mother of pearls have been cherished for their decorative qualities since early civilisation and peaked in popularity during the Victorian era. Today, the world has once again opened its eyes to the striking properties of this stunning gem.

Mother of pearl (or nacre) is not an actual pearl, but rather the pearly inner layer found within certain types of mollusc shells.


Mother of pearl belongs to a small group of gemstones classified as organic gemstones, just like the pearl. Mother of pearl (or nacre) is the pearly internal layer found within certain mollusc shells. Consisting mainly of calcium carbonate, it is created by the mollusc as a way of protecting itself from parasites. Mother of pearl has a platelet structure which reflects light waves and produces its renowned iridescent sheen.


After the mother of pearl is cut from the shell of the oyster, it is sometimes bleached to produce a uniform white colour or dyed a range of attractive colours. A light polishing is applied to accentuate the pearlescent effect. Mother of pearl is often cut into fancy shapes for jewellery use. Shaping can be done by hand in traditional manner or achieved using modern laser cutting technology (CNC). In ancient times, mother of pearl was also used for mosaics, created with tiny pieces of the luminous gem.


The unique lustre of pearls and mother of pearls have made them cherished throughout history.



Mother of pearl has been a cherished adornment in jewellery and design for thousands of years. It was treasured by the ancient Egyptians and Sumerians, as well as the Victorians, who used it to creating exquisite inlays on cutlery and decorative buttons. In the 1880s, the leaders of the London street traders began to decorate their suits with hundreds of mother of pearl buttons in order to highlight their fundraising activities. They subsequently became known as “Pearly Kings” and “Pearly Queens.” The tradition continues to this day, where mother of pearl is also used to decorate musical instruments and watch dials. Significantly, it has experienced a revival as an eye-catching jewellery component.

Mother of Pearl Mosaic

The lustrous and iridescent appearance of mother of pearl is fully realised with the Pandora mosaic charms. The spectacular designs combine over 4,000 years of history with a modern aesthetic. Creating the mosaic charms involves a labour of love just like their ancient counterparts. Each design is a small work of art brought to life in a process that requires more than 18 different steps. Highly skilled craftspeople use traditional techniques to carefully arrange the small mother of pearl pieces that are shaped as small squares or moons and stars, piece by piece onto a resin or acrylic base using a special adhesive. The colour of the base enhances the natural colour of the gem. The piece is then baked in an oven to allow the adhesive to cure and strengthen the bonding. The final step is polishing the mosaic charms to create a high shine and assembling it with the sterling silver core.
