Calcite (var. helictite)

This specimen is a bizarre and beautifully shaped stalactitic grouping of crystallized calcite from Bisbee, Arizona. While Bisbee is best known for its superb copper minerals, it has also produced a variety of other iconic species, including these calcite formations.

This piece features a colourless, cave-growth calcite with excellent translucence, and a dramatic, flowing sculptural form dominated by a central, thick, amorphous cone. Below it are two curved forms, making for an aesthetic grouping. The structure is known as a helictite—cave formations that deviate from vertical growth, creating curved or angular shapes that seem to defy gravity. It is accented by a subtle bluish-green hue, adding an attractive tint to the piece. While it is unclear if this specimen fully qualifies as a true helictite, it certainly exhibits similar visual characteristics.

Historically, most of Bisbee’s underground orebodies had caves above them, and miners occasionally recovered specimens from these now largely inaccessible formations. The specimen remains in excellent condition, and has a bit of hardened clay on the bottom which allows it to stand on its own.
