Collection: visible light

Our Visible Light collection features seven different gemstones representing each color of the rainbow: red carnelian, orange aventurine, citrine, green aventurine, apatite, lapis lazuli, and amethyst. This collection explains how white light separates into its component colors when refracted through water droplets, creating the phenomenon we know as a rainbow. When it's separated, we see the spectrum: Red, Orange, Yellow, Green, Blue, Indigo, and Violet (ROY G BIV). Then, the light reflects off the back of the droplet and exits. Different colors exit at slightly different angles, creating the arc we see. Red light has the longest wavelength and violet has the the shortest, explaining why red always appears on the outer edge of a rainbow and violet on the inner edge.
