Rock Crystal

Quartz that is colorless, transparent, and has intact crystal faces is called crystal. 「Quartz」 This name has been in use since around the 16th century, and some believe it originated from German vocabulary related to mineral deposits Rock Crystal This word has a history of over 2000 years. 「Crystal」 Derived from the Greek word for ice, which means' crystallos'. At that time, people believed that crystals were fossils of ice, so the literal meaning of 'Rockcrystal' was' ice like '. And 'crystal' originates from 'water spirit' in Japanese, and the concept is similar to the above, which is very interesting. Quartz has a low refractive index and dispersion, making it mediocre and not particularly outstanding as a gemstone. But due to its lack of cleavage, it is relatively advantageous during the cutting process. Before people knew how to make transparent glass, crystal was usually a transparent material for making beads, containers, and lenses. Even with the emergence of transparent glass, crystals still hold an unshakable position due to their superior hardness compared to ordinary glass.
