This pendant depicts the guard cells of a stoma (plural 'stomata'), a pore on the surface of the plant that facilitates gas exchange for the plant. Through the stomata, plants take in carbon dioxide for photosynthesis and respire oxygen. The opening and closing of the stoma is regulated by osmotic pressure in the guard cells and is dependent on carbon dioxide concentration, light intensity, humidity and other environmental factors. The guard cells depicted in this pendant show the large nucleus in each guard cell as well as the chloroplasts. Designed in collaboration with Prof. Keiko Torii, University of Washington.
The pendant is 1.3 cm long below the loop.
The pendant is 3D printed in solid sterling silver or 14K gold plated brass, 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.
*While a 45 cm/18 inch fits most, other chain lengths are available. At checkout, write a note indicating your preference.
