It is found only in one small area of Tanzania, near Mount Kilimanjaro, and is known for its unique blue hues, often with violet or purple undertones. Its price and availability are directly linked to the mines in this region.

Key Characteristics:

Color:

Primarily blue, ranging from pale blue to intense ultramarine, often with violet or purple undertones. Some stones exhibit a reddish hue due to pleochroism.

Pleochroism:

Tanzanite displays different colors when viewed from different angles, which is an important factor in cutting and value.

Heat Treatment:
