As I mentioned earlier, not all crystals and stones are ideal for making elixirs. This is because some stones and crystals don’t take well to water. Some dissolve, some rust, and others flake apart.
Stones and crystals that dissolve in water include calcite, halite, labradorite, selenite, ulexite, and carnelian.
Galena, hematite, and lodestone should not be used because they will rust when exposed to water.
Crystals and stones that can flake away in water or suffer from cracks and fractures include lepidolite, malachite, mica, moldavite, muscovite, opals, pearls, turquoise, and obsidian.
Pyrite should NEVER be used to create an elixir because when it is combined with water it creates sulfuric acid.
A word of caution: crystal elixirs are not meant to replace any medications that you may need to take for medical reasons. There are also crystals that should not be used in elixirs, specifically those that contain harmful substances, such as lead, mercury, arsenic or aluminum.
