Topaz: November’s Birthstone

The November birthstone is topaz, a lustrous gem that spans from fiery orange to icy blue, with many magnificent shades in between. It is a silicate mineral of aluminum and fluorine with the chemical formula Al2SiO4(F, OH)2. The name topaz comes from Topazios, the old name for an island in the Red Sea. However, no topaz was ever produced on Topazios!
