This solid silver ring, inspired by the atom, is a perfect gift for your favorite chemist. According to the Australian band Cat Empire, we're all just protons, neutrons, electrons. Even if you're not a fan of the Empire, wear this ring in solidarity with every atom in your body. Marvel at how the electron orbitals stubbornly defy the rules of 3D-printing! Based on the Rutherford-Bohr model of the atom.

The ring is made to order in your size by 3D-printing 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. Sizes listed are in US ring sizes.

While some items are in stock and can be shipped immediately, others require 2-3 weeks for 3D-printing. Item will ship insured by registered mail.

All items are gift-wrapped in original, recycleable Ontogenie packaging.
