The Mineral With the Most Forms
• Innumerable Habits
• Stunning Twins
• Cave Formations
To collectors, the word calcite invokes thoughts of shape and for good reason:
calcite is found in more habits than any other mineral. It has fascinated crystallographers for generations.
• Polarization
• Wave Theory
• Ring Sights
Over its long history, calcite has been instrumental in shaping the worlds of microscopy, architecture, mineralogy, technology, physics and even the science of war.
• Favorite Fluorescence
• Dazzling Gemstones
• Colorful Combinations
Pure calcite is colorless, but even trace impurities can bring intense color to its many forms. The correct cut can transform common calcite into a stunning gemstone
