This pendant is based on Spumellaria, a type of Radiolaria. Radiolaria are aquatic protozoan life forms that develop a fantastically intricate silica-containing shell. The sea floor is composed of their microscopic fossilized skeletons. The Radiolarian 'Spumellaria' is defined by its elaborate sphere-within-a-sphere construction. The delicate spines on the shell are important for the buoyancy of the plankton during its lifetime, but break off when the shell is deposited in the sea bed. This design was inspired by a drawing by the German naturalist, Prof. Ernst Haeckel.

The pendant is approximately 4.2 cm in diameter, including spikes.

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

The pendant is 3D printed in solid sterling silver or bronze, 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. 

*While a 45 cm/18 inch fits most, other chain lengths are available. At checkout, write a note indicating your preference.
