New Zealand Rainbow Pāua (Abalone) Shell Beads – Tumbled Polished Centre Drilled (Pack of 20)

A pack of New Zealand rainbow Pāua shell (abalone) beads, tumble polished and centre drilled for jewellery making, beadwork, and craft design. Each bead displays the natural iridescent colour play that Pāua shell is known for, ranging from deep ocean blues and greens through to violet and pearlescent highlights.

Material & Identity

Pāua (Haliotis iris) is a marine abalone species native to New Zealand, recognised for its highly iridescent nacre layer (mother-of-pearl). This internal shell layer produces its characteristic rainbow-like appearance, formed entirely through natural biological structure rather than surface pigment.

Formation & Science

The iridescence of Pāua shell is produced by nacre microstructure, composed of microscopic aragonite (calcium carbonate) platelets arranged in tightly stacked layers. Light interacts with these layers through refraction and interference, creating structural coloration—responsible for the shifting blues, greens, and purples seen across each bead.

Tumble polishing smooths the shell surface while preserving the internal nacre structure, enhancing light reflection and revealing natural variation in tone and depth.

Cultural & Natural Context

Pāua is a well-known natural material in New Zealand, historically used in both traditional and contemporary carving and decorative arts. It remains a widely recognised shell in modern jewellery design due to its strong visual impact and organic connection to marine environments.

Craft & Use

These beads are centre drilled, making them suitable for a wide range of jewellery applications including:

* necklaces and bracelets
* bead weaving and stringing projects
* mixed-media craft work
* decorative design accents

Each pack contains 20 naturally varied beads, ensuring subtle differences in colour, shape, and iridescence while maintaining consistent usability for jewellery making.
