Calocyclas is a marine protist from the class Radiolaria. The single-celled amoeboid inhabitant and maker of this shell feeds by extruding pseudopods out through the holes in the shell, snagging prey and dragging it into the shell to be devoured. Ernst Haeckel described its shape as "a three-chambered shell; head with a strong, three-sided horn, bell-shaped thorax protected with many long radial spikes, and a wide abdomen with a wreath of many large vertical feet."

This a large pendant, measuring 4.6 cm (1.8 inches ) tall by 3.3 cm (1.3 inches) wide, including spikes.

This pendant has sharp points and should be worn with caution.

The pendant is 3D printed in lightly polished solid sterling silver, bronze or brass, finished with a 45 cm/18 inch long sterling silver or rose gold plated silver chain, and is ready for gift giving with a gift box, polishing cloth, and care instructions.
