Crystal Structure

Tanzanite crystals have a triclinic crystal structure, which means that they have three unequal axes and three angles that are not all right angles. This complex crystal structure is what gives tanzanite its unique optical properties, such as its strong pleochroism (the ability to change color depending on the angle at which it is viewed).

Color

The color of tanzanite is caused by the presence of vanadium impurities. The more vanadium present, the deeper the color of the tanzanite. Tanzanite can range in color from light blue to deep violet, with the most desirable colors being deep blue and violet-blue.

Clarity

Tanzanite is typically found with inclusions, which are tiny flaws or imperfections in the crystal. These inclusions can be seen with the naked eye or under magnification. The clarity of tanzanite is graded on a scale from IF (internally flawless) to I3 (included). IF tanzanite is the most valuable, but it is also the rarest.

Cut

Tanzanite is typically cut into a variety of shapes, including round, oval, cushion, and emerald. The cut of a tanzanite can affect its appearance and value. A well-cut tanzanite will maximize the stone's color and brilliance.
