Malachite is a carbonate mineral of copper, which as you probably know is great at conducting energy. Malachite has been used by ancient cultures as a very transformative stone including the Ancient Egyptians, who used the power of malachite to effect great change within their physical bodies, believing it helped to heal at the cellular level. They used it in jewelry & carved ornaments out of it. With its green colors, It is associated with the heart chakra (energy center) in the body but also said to help cleanse and clear all chakras. It is thought that the more bullseyes a piece has the more powerful it can be energetically.
These particular piece is from the earth in The Democratic Republic of the Congo, where it was ethically mined and polished into the sphere shape. The sphere shape is said to emit energy in all directions. They are labeled A-D, (largest to smallest) please make a selection and the correct photo should populate. Each one is incredibly unique, with fascinating lines and natural designs, please see photos there are some deep groves and exposed parts of the sphere, very hard to capture! They are very heavy and grounding for their size, felt like a weighted blanket of energy when I held them. They measure around 2.5 inches in diameter.
