Spumellaria is a type of Radiolaria, an aquatic protozoan life form that forms a fantastically intricate silica-containing shell. The sea floor is composed of their microscopic fossilized skeletons. Ontogenie Design allows you to view and wear the shells of these amazing creatures, in three dimensions, without the aid of a microscope.

This version of the pendant lacks spines. These delicate spines, while useful for the buoyancy of the plankton during its lifetime, often break off when the shell is deposited in the sea bed.

The jewelry is created by 3D-printing in wax followed by metal casting in solid bronze, solid brass or solid sterling silver. They are lightly polished after casting to give them a smooth glossy texture. The gold-plated stainless steel is created by 3D-printing followed by bronze infusion and baking in a kiln, and finally, plated in gold.

To prevent waste and overstock, the jewelry is not made until you order. Please allow 3-4 weeks for printing and shipping. All items are gift-wrapped in original, recyclable Ontogenie packaging and then shipped insured by registered mail, worldwide.

The pendant will be shipped with a rose gold-plated, gold-plated or non-plated sterling silver anchor chain depending on whether you order the bronze, brass or silver pendant.

The pendant is approximately 3cm in diameter.
