These authentic Red Abalone shells (Haliotis rufescens) originate from the rocky kelp forests of the Pacific West Coast, ranging from Oregon to Baja California. As the largest abalone species globally, they feature a robust, dome-shaped body structure composed of a "brick-and-mortar" calcium carbonate matrix, making them exceptionally durable. The exterior showcases 3 to 4 slightly raised respiratory pores and a rustic red finish, while the interior reveals a smooth, iridescent nacre with a prominent central muscle scar. A perfect coastal masterpiece to elevate your space.
