The Discosphaera earrings are based on the unicellular phytoplankton coccolithophore, Discosphaera tubifera. In comparison to the coccolithophore Coccolithus pelagicus, the coccolith plates on this alga are uniquely trumpet-shaped. The trumpets are composed of calcium carbonate. Coccolithophores are photosynthetic and thus found at the sunnier depths of the ocean.
These earrings will ship from Shapeways without earring hooks. The hooks shown are rose gold-plated sterling silver.
