At a base level, Amethyst is renowned for bringing a sense of calm and clarity to our chaotic world. Those who keep Amethyst close will find that they feel comforted, grounded and soothed in a truly uplifting way. Because Amethyst centers the emotions, it can be a beautiful aide in recovery for those suffering from the overwhelming emotions that come with grief, loss and all shades of sadness. Thanks to its divine spirituality, it’s a great stone for reminding people not to fear the unknown.
Amethyst is a variety of quartz and its chemical makeup is composed of silicon dioxide. Quartz is formed in lava, specifically when gas bubbles become trapped, allowing crystals to form inside the cavities created by the bubbles. When the cavities are filled with a silica-rich liquid, crystals begin to form within volcanic rocks
Like other quartz, amethyst grows in or around extrusive and intrusive igneous rocks, metamorphosed rocks, hydrothermal veins, and hot springs. Once hot thermal water cools, it crystallizes and can form amethyst.
(It  can takes millions of years to form the crystals) which I think is absolutely incredible!
