Ceratium Dinoflagellate Earrings

Regular price167.00 €
Tax included. Shipping calculated at checkout.


These funky horned earrings are inspired by the dinoflagellate genus Ceratium. Dinoflagellates are unicellular eukaryotes that use flagella for locomotion. They live in both freshwater and marine aquatic environments. Ceratium is an especially beautiful genus characterized by two flagella, armored plates and two curving horns. Some species of Ceratium are red to brown in color due to photosynthetic chromatophores in their cytosol.

The Ceratium Dinoflagellate Earrings are 1.9 cm in length below the loop, 1.9 cm wide and each earring weighs 3.2 g.

The earrings are available in solid sterling silver or polished brass, finished with nickel-free sterling silver or 14K gold plated silver hooks, and are ready for gift giving with a gift box, polishing cloth, and care instructions.
