Crystal is a colorless and transparent large quartz crystal mineral. Its main component is silicon dioxide, which is called "water spirit" in Buddhist scriptures. I think it will shine magic light. In our daily life, crystal is also our favorite. It can not only be worn by ourselves, but also be given away.
Amethyst represents the constant love, and is often used as a love stone between lovers. It also represents the guardian stone of love in western countries, which can give deep love to lovers and couples. The main functions of Amethyst are: calming emotions, helping thinking, concentrating and increasing memory.
