What is the difference between Abalone and Mother of Pearl?

Abalone and mother of pearl are two different materials that come from sea creatures. Each one has its own unique characteristics that make them special.

Abalone is a type of edible sea snail found in coastal waters, while mother of pearl is the shiny inner lining of mollusk shells, including abalone shells.

We will explore the main differences between abalone and mother of pearl. Let’s dive in and discover what makes these natural materials so interesting!



Abalone are a type of gastropod shellfish, known for their striking ear-shaped shells.

These shells can find in different size, from a few centimeters to up to 30 centimeters.

They are often characterized by their row of holes or respiratory pores, which the abalone uses for expelling water and waste.

Abalone shells find in different colors, from deep blues and greens to vibrant pinks and purples.

These beautiful shells are made of calcium carbonate, which the abalone secretes as it grows.

The shell’s many layers create a strong, protective barrier for the abalone, allowing it to survive in harsh marine environments.

Each layer consists of microscopic platelets, which give the shell both its unique iridescence and remarkable strength.

  • Appearance: Abalone shell features a rough exterior with vibrant, iridescent colors on the interior.
  • Texture: The outer surface is rough and textured, while the inner surface is smooth and shiny.
  • Composition: Abalone is primarily composed of calcium carbonate and aragonite, with the mother of pearl layer lining the interior of the shell.

Mother of Pearl

What is Mother of Pearl

Mother of pearl, also known as nacre, is the iridescent internal layer found within the shells of certain mollusks, including abalone and pearl oysters.

This smooth, shimmering substance is composed of microscopic, hexagonal calcium carbonate platelets, which are held together by a protein matrix.

This arrangement provides strength, resilience, and flexibility to the nacre.

While both abalone shells and mother of pearl share the trait of iridescence, they differ in terms of their prominence in the mollusk’s shell.

In abalone shells, the iridescence is present throughout the entire shell, while in other mollusks, mother of pearl is typically confined to the inner layer.

  • Appearance: Mother of Pearl exhibits a pearly luster with varying tones of color, usually white, cream, or silver.
  • Texture: Smooth and lustrous, with a subtle wave-like pattern.
  • Composition: Mother of Pearl is primarily composed of calcium carbonate and aragonite and is the innermost lining of mollusk shells, including pearl oysters, freshwater pearl mussels, and abalone.
