Baculogypsina is a Foraminiferan, a single-celled marine organism with a calcium-containing shell. This creature provides the whimsical star-shaped shells of the ‘star sand beaches’ of Japan, and contributes to the stabilization of coral reefs in the Pacific Ocean by depositing calcium carbonate onto the reefs. Baculogypsina was drawn by Ernst Haeckel as a perfectly symmetrical 5-pointed star, but in nature these creatures usually have a jaunty, irregular shape like these 3D-printed earrings.
Baculogypsina makes a pretty pendant if you add a jump ring and a chain. To purchase a pair for earrings, please see the item "Baculogypsina earrings" in this shop.
Earring hooks, jump rings and chains are not provided by Shapeways.
