The November birthstone is Topaz. In antiquity all yellow gems were known as topaz, but in modern times the name is given only to a particular form of silicate.
Pure topaz is colourless but is usually tinted by impurities. Gem quality stones can be seen ranging in colour from blues to pinks and reds to yellow. The colours most often associated with topaz are the beautiful yellow and orange hues which are also seen as a symbol of friendship.
