DICHROIC GLASS DUAL ADJUSTABLE RING
This reflective phenomenon is known as thin-film physics, which is also why you see swirling rainbow patterns in a soap bubble, floating colors from oil on water and the dramatic colors of dragonfly wings.
Dichroic glass is not reflective because of special glass or textures. Instead, it is a special coating treatment that is done to the glass. This beautiful glass represents an adaptation of aerospace technology to the world of art. NASA originally developed dichroic glass for use in satellite mirrors in the early 1990s, and also uses it for re-entry tiles on space shuttles.
