Aurora borealis, the Northern Lights, is a phenomenon that can only be seen in some of the world's quietest, darkest, and most remote places. The fact that they shine brightest in dark and barren places is symbolic of a love that grows stronger in the face of suffering and adversity. Various colors and wavelengths are produced by a combination of gold and other metals. And delicate textures cause light to pulsate and diffuse beautifully. The effect is one of metal woven with light, symbolizing a strong and lasting love.
