Czech Republic Chalcanthite

There's much skepticism about whether these are lab grown or natural. I got this from a reputable store, and even they weren't sure if their supplier was being truthful, which leads me to believe this stone is lab grown. Chalcanthite's most distinctive property is its solubility in water. When exposed to moisture or humidity, the crystals can dissolve. It is low hardness, making it quite fragile. It is also indigestible, due to its toxicity. It's connected to the throat chakra, making it a useful tool for communication. It is believed to promote the flow of energy and assist with emotional healing. Chalcanthite will help move stagnant energies. It supports a strong will to stay focused. It will support your confidence in making decisions.
