Tanzanite

A large cluster of two shiny tanzanite crystals with the most prized dark blue-violet color. The color change is very pronounced in this specimen. The tanzanite crystals have minimal damage, located on the smaller crystal in the lower front part of the specimen and on the left rear part of the left crystal. The crack in the upper third of the specimen has been repaired. The shiny surfaces of the tanzanite crystal are covered in places with parallel aggregates of white calcite. This specimen is unusual in its complexity and multiple surfaces that form the upper ends of the crystals.
