Many girls naively think that popular Chanel strands are made from the natural pearl. The shining surface makes you believe it is a pearl, but it is not.
In fact, the Chanel strands are made of glass jewelry. Every single bead is blown from glass and put to the natural nacre from shells under a very high temperature. Because of natural nacre this pearl shine appears, so you can think you see the real pearls. Chanel strands are timeless because the nacre will never darken. This is a good way to save money for fashionistas - those pearl strands will never go out of fashion.
"Pearl" strands became a symbol of Chanel and they're often used to draw customers' attention as it was made in Tokyo. Huge strands were put in window displays.
