Piezoelectricity is one of the most fascinating electrical properties found in certain minerals. When mechanical pressure is applied to specific crystals, they generate a small electrical charge. Conversely, when an electric field is applied, these crystals can change...

Double refraction, also known as birefringence, is one of the most important optical properties used in mineralogy and gemology. It occurs when light entering certain minerals splits into two separate rays that travel at different speeds and in different directions....
