How do amethysts geodes form? Amethyst formation is a two step process: 1. Air pockets are created when molten lava settles. These air bubbles form a solid rock enclosure which creates the conditions for the crystal forming process to occur. 2. Silica~rich liquid that contains minute amounts of iron. Over time, this composition forms six sided pyramids which we know to be amethyst crystals. Today most high quality amethyst crystals are found in South America with the best specimens being from Brazil and Uruguay. Amethyst has been highly prized throughout the millennia both for it’s beauty and it’s perceived healing properties. The Ancient Greeks believed that the crystal kept the wearer from getting intoxicated and today the stone is revered for it’s ability to improve cognitive function. Whatever the use, amethyst is no doubt one of the most stunning natural phenomenons out there.
