"Hand-crafted from solid sterling silver, my Neuron Ring makes the perfect STEM statement! To make this ring have extra meaning, I chose to keep the Myelin Sheaths open to resemble an infinity symbol. A great symbol for infinite love of the mind, body and science! The ring comes lightly hammered, giving it facets that reflect sparkling light. If you wish to have the ring without hammering, choose the \"Without Hammering\" finish in the drop-down menu. The ring is adjustable which is great for wh Biology Ring, Neurons Firing, Science Inspired Jewelry, Brain Necklace, Math Jewelry, Science Jewelry, Sparkling Lights, Science Themes, Science Gifts
