Tanzanite is a stunning blue-violet variety of the mineral zoisite, found only in Tanzania, which is how it got its name. It was discovered relatively recently in the 1960s and has since gained popularity for its unique color, which can range from a rich, deep blue to a lighter, more violet hue, often displaying a remarkable pleochroism—showing different colors when viewed from different angles.

In terms of hardness, tanzanite scores about 6 to 7 on the Mohs scale, which makes it somewhat softer than other gemstones, so it requires careful handling to avoid scratches. As a gemstone, tanzanite is often associated with spiritual awareness and transformation, believed to help in communication and self-expression.
