Amethyst is the most popular variety of quartz crystals that is considered the most powerful and protective stone. It is a semiprecious violet stone that is often used in jewelry and for healing purposes. 

Amethyst is known as an "air" element that provides calm and positivity to those who wear or use the stones or crystals. As The Tennessean reported in March, the stone is considered a calming material that also helps those struggling with substance abuse. Amethyst works to bring tranquility to your mind and your crown chakra so you can focus on healing any blockages that are holding you back from experiencing bliss.

Your seventh chakra is purple and is known as the crown chakra because it's at the very top of your head. The crown chakra is your personal connection to the divine. The crown chakra is also known as the bliss chakra because it aligns your mind with pure consciousness and wisdom.
