The Discosphaera earrings are based on the unicellular phytoplankton coccolithophore, Discosphaera tubifera. In comparison to the coccolithophore Coccolithus pelagicus, the coccolith plates on this organism 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 elegant earrings are 1.8 cm in diameter below the loop, and each earring weighs 4.1 g.
The earrings are available in lightly polished solid sterling silver or bronze, finished with nickel-free sterling silver or rose gold plated silver hooks to match, and are ready for gift giving with a gift box, polishing cloth, and care instructions.
