These earrings depict the guard cells of the stomata, pores on the surface of the plant that facilitate 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.

Each earring measures 1 cm in the longest dimension (top to bottom) and the post diameter is 1 mm.

The earrings are available in sterling silver or 14K gold plated brass and finished with nickel-free earring backs (not shown).

tick silver earrings

Ontogenie jewelry is 3D printed in wax and then cast in solid sterling silver, solid brass and solid bronze as well as gold-plated brass. The silver and bronze pieces, and to a lesser extent brass, will tarnish and discolor slightly over time. This is completely normal for these materials. Since moisture tends to accelerate the tarnishing process, I recommend that you don't wear the jewelry in water, e.g., while bathing, showering or swimming. The oils in your skin will also contribute to tarnishing. I recommend polishing the jewelry with a soft cloth after wear and storage in a dark, dry place to slow the oxidation which causes tarnish.

If the jewelry should tarnish, I've found that it can be returned to its original brilliance and color by using a gentle, nonabrasive silver polish. The more detailed and highly textured pieces will be more difficult to polish because of surface variations. To polish these, I recommend using a very soft toothbrush with the silver polish to allow cleaning of small crevices. After polishing, you can remove excess polish by rinsing the jewelry in water and then washing the piece in with a gentle detergent followed by a final water rinse.

The gold-plated materials, however, should not be vigorously polished as the plating is likely to wear off over time. The gold-plated materials are much less susceptible to tarnishing and will probably never need to be polished.

All of the jewelry should be protected from impact against hard surfaces as this could cause scratches.
