I recently received an amethyst crystal as a gift and I was wondering if I can use it in water. I have heard conflicting opinions from different people and I am not sure what to believe. I want to use it as a decorative item in my water feature in the garden but I am worried if it would cause any harm to the crystal or the water. Can anyone shed some light on this topic and let me know if amethyst can go in water? If not, what would be the best way to use it as a decorative item without damaging it?
