The wavy turban snail is a marine gastropod mollusk belonging to the prestigious Turbinidae family. Native to the rocky shores of the California coast, it stands as one of the largest gastropod shells found in Southern California. 

In nature, the shell is composed of a thick, brilliant inner nacreous (mother-of-pearl) layer beneath a porcellanous layer, protected in life by a dark brown periostracum. The cleaned shells offered here showcase the magnificent twisted ridge at the outer edge of each whorl, alongside coarsely sculpted fine knobs and an arcuated columella with a pearly groove.
