This ring is based on the structure of Skeletonema species, a genus of diatoms found in all coastal waters except for the polar regions. Skeletonema diatoms are colonial, forming long filaments stabilized by exterior struts, and like all diatoms, they are photosynthetic. Ontogenie has crafted this colonial diatom into a lovely sterling silver ring.

The ring is made to order by 3D printing in wax and casting in polished brass, bronze or silver. If you require a size not listed, please contact me. I will be happy to create your size and make it available for purchase. If you don't know your ring size, it's best to have your size professionally measured with a ring sizer at your local jeweler.

The ring is 3D printed in polished solid sterling silver and is ready for gift giving with a gift box, polishing cloth, and care instructions.

Turned the first day

This ring was really pretty, I wore it one day and it turned blue.

I'm so sorry to hear this! I've never had a customer report a sterling silver ring turn blue. Can you please send me a photo? Certain chemicals and hand sanitizers can cause bronze to become green, but I've never had a problem with silver. I would recommend polishing it was a gentle silver polish. If that doesn't help, please contact me and I will give you a full refund. --Kimberly
