Amethyst (Amethyst)

Amethyst is the birthstone for February. It is the name for purple quartz, and its Japanese name is "Murasaki Suisho." It is said to have been named after the Greek word "amethystos," which means not to get drunk, and it also appears in Roman mythology. It is often cut in a special way, making it a fun gem to collect in various cuts.
