What Chakra Is Malachite | 25+ Meanings and Properties
Malachite is a mineral formed in the Earth's crust when water containing carbon dioxide interacts with minerals like copper. Over time, these elements undergo a transformation, resulting in the creation of malachite. This process, although slow, is immensely powerful and reflects the enduring resilience of nature.
