⚠ Handle With Care Low caution
Why: Copper carbonate hydroxide. Polished pieces are safe to handle. Its dust, from cutting or polishing, is harmful to breathe or swallow, and it is not suitable for water elixirs.
Safe handling: Handling and wearing it is fine. Cut or polish it only wet with a mask, and don't make elixirs.

✨ Metaphysical & Folklore
💧 Elixir safety: This stone is not safe for water or drinking elixirs. If you use elixirs at all, use the indirect method (stone in a sealed glass inside the water) or choose a different stone.
These are traditional and folk beliefs from crystal lore. They are not scientific or medical claims – crystals are not a substitute for professional care.
With bold green bands, malachite is known as the stone of transformation and protection.
