Topaz is allochromatic, which means that its colour is caused by impurity elements or defects in its crystal structure rather than by an element of its basic chemical composition.

DECEMBER - TANZANITE & TURQUOISE
Tanzanite is the birthstone for December and has a hardness of 6.5. Tanzanite is the blue to violet to purple variety of the mineral zoisite. It is mined commercially only in one area of the world: the Merelani Hills of Tanzania, which is where it gets its name. Tanzanite’s appearance is influenced greatly by its pleochroism, which is the ability of a gemstone to show different colours when viewed in different crystal directions. Tanzanite can be violetish blue—similar to a sapphire colour—or much more purplish.
