Speed of Light Necklace

The speed of light is a fundamental constant of the universe. It represents a core principle of physics, astronomy, and our understanding of reality. Meter by meter and second by second... whatever your goals are, may light to inspire you to push forward and give your best!

This pendant measures 1.5 inches in length and is made from platinum or gold-plated steel. It comes on a sterling silver or gold-plated chain, in your choice of a 16 inch or 18 inch length. Choose 16 inches for a short, layering-style necklace, or 18 inches for a standard-length necklace. [As a note, we asked an ultra-marathoner friend to try it out for us... She reported it to be both sturdy and so comfortable she forgot she was wearing it.] All U.S. orders come in a beautiful hand-stamped gift box. International orders come in a black velvet drawstring bag.

Perfect for:

  • Astronomers, physicists & science enthusiasts
  • Runners & athletes
  • Ambitious, high-energy achievers of all kinds
