Ancient Egyptians carved many items out of calcite, relating it to their goddess Bast, whose name contributed to the term alabaster because of the close association.
Many other cultures have used the material for similar carved objects and applications.

A transparent variety of calcite known as Iceland spar may have been used by Vikings for navigating on cloudy days.

High-grade optical calcite was used in World War II for gun sights, specifically in bomb sights and anti-aircraft weaponry.
Also, experiments have been conducted to use calcite for a cloak of invisibility.

Microbiologically precipitated calcite has a wide range of applications, such as soil remediation, soil stabilization and concrete repair.

Calcite, obtained from an 80 kg sample of Carrara marble, is used as the IAEA-603 isotopic standard in mass spectrometry for the calibration of δ¹⁸O and δ¹³C.
