Coccolithophore 'Coccolithus' Pendant

Regular price132.00 €
Tax included. Shipping calculated at checkout.


The Coccolithus pendant is based on the complicated structures of coccolithophores, specifically Coccolithus pelagicus. The shell of this unicellular phytoplankton is composed of interlocking plates, called coccoliths, composed of calcium carbonate. Occasionally, huge increases in coccolithophore populations, called 'coccolithophore blooms' are evident as massive patches of turquoise color in the ocean that can be seen in satellite photos of the earth. Although blooms appear to be happening more frequently with global warming, the carbon fixation by coccolithophores could potentially reduce carbon dioxide concentration in the atmosphere and therefore counteract the effects of global warming.

The pendant is 2.7 cm (1.06 inches) in diameter.

The pendant is 3D printed in lightly polished solid sterling silver or bronze, finished with a 45 cm/18 inch long sterling silver or gold plated silver chain and is ready for gift giving with a gift box, polishing cloth, and care instructions. 

This pendant, without chain, can also be purchased from my Shapeways shop: Coccolithus Pendant

Excellent Product

The necklace exceeded expectation. However, the delivery service was awful. UPS are a terrible company. It's taken over a month, plus several phone calls and a late payment fee, to pay the import fees they charged.
