HISTORY OF THE DECEMBER BIRTHSTONE
Pure topaz is colourless and allochromatic, meaning it has a range of colour possibilities it has been found as a pale green, blue, and yellow. The paler the topaz is, the more expensive it will be. December’s blue shade is one of the rarest occurring in nature. Most people recognize the precious blue topaz for its alluring aqua-turquoise shade. The three main shades of this range are known as London Blue, Sky, and Swiss. The alternative to the blue topaz is the turquoise. Today, its primary source is Brazil, although it is also found in Sri Lanka, Mexico, Australia, and parts of Mexico.
