The listing, Emerald & Silver Dichroic Glass Pendant Bead has ended.

Gorgeous emerald green and silver dichroic glass pendant bead. Flat on the back and rounded on the front with a depth of about 3/8". Photos don't do this justice.

Dichroic (pronounced dye-crow-ick) glass, commonly called dichro for short, literally means ''two colored'' and is derived from the Greek words ''di'' for two, and ''chroma'' for color. It was thus named because of its fantastic multi-colored and reflective properties. When you look at this glass, it appears to have more than one color at the same time, especially when viewed at different angles.

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.
