Calliostoma turbinum is a species of sea snail, a marine gastropod mollusk in the family Calliostomatidae.

[2][3] The shell is small, turbinate and thin.

The nacre shines with a peculiarly coppery luster.

The periphery is painted with purple-brown flammules and the spirals are more or less articulated with the same color.

[4] This species occurs in the Pacific Ocean from Point Conception to San Diego, California.
