Here is a list of crystals that can go in water, and more specifically, that are safe for a crystal water bottle or other form of ingestion. As with the water-unsafe crystals, this list is not extensive. You can create water bottles with crystals that are not on this list, just make sure you research them before drinking any crystal-infused water.
- Amethyst
- Black Obsidian
- Carnelian
- Citrine
- Clear Quartz
- Rose Quartz
- Rutilated Quartz
- Smoky Quartz
The Quartz family stones, namely Quartz crystal, Amethyst, Citrine and co, are all generally safe to put in crystal water, so start with Quartz crystals if you’re looking for water-safe crystals for your gem elixirs.
