calcite

Calcite is a gemstone that is also famous for its strong ``doubling'' (birefringence), which causes lines to appear double when placed over letters. In addition, it is said that it has a property called ``cleavage'' that makes it vulnerable to impacts from specific directions, and it is said to have an extremely perfect property called ``cleavage'' in three directions, and it is said that if you hit it, no matter how small it is, it will break into diamond-shaped pieces like a crushed matchbox. . Legend has it that Vikings once used it as a compass.
