Mother of Pearl

About Mother of Pearl

Mother of pearl, or nacre, is an organic-inorganic composite produced by molluscs. It lines the inner surface of shells, where it serves as a protective layer. Nacre is composed of microscopic platelets of aragonite (a form of calcium carbonate) arranged in a brick-like pattern and bound together by organic biopolymers. This layered microstructure produces the characteristic iridescent rainbow shimmer.

Formation & Origin

Unlike mineral stones that form over geological timescales, nacre is produced by living organisms over the course of years. Abalone, oyster, and nautilus shells are the primary sources for architectural-grade mother of pearl. The iridescence is a structural colour effect — thin-film interference from the precisely spaced aragonite layers, each approximately 500 nanometres thick, selectively reinforces certain wavelengths of light.

Why Mother of Pearl for Interiors

Mother of pearl brings a luminous, oceanic quality to interior spaces. Its iridescent surface shifts between white, cream, pink, green, and blue depending on the viewing angle and lighting. When backlit, it glows with a soft, warm light that feels organic and calming. It is particularly popular in bathrooms, where its aquatic origins feel naturally at home, and as backsplashes in kitchens and bars.

Sustainability

We source mother of pearl from sustainable aquaculture operations and as a by-product of the food industry. No molluscs are harvested solely for their shells. Our supply chain prioritises operations with documented environmental management practices and fair labour standards.
