Hydrogen gas, when excited, emits characteristic colors. The colors of the hydrogen spectrum inspire this necklace - violet amethyst, turquoise and red coral. Hydrogen has a "line spectrum:" the bands of color are very narrow, hence the use of rondelle beads. There are dark regions in between, indicated by hematite beads.What an awesome and artistic depiction of an important chemical property!
