The mineral rhodonite occurs in various shades of pink to deep red. Often included with manganese oxides, these black patterns can present as fracture fillings, be part of the rock matrix (the rock in which the rhodonite is embedded) or can also be dendritic. Although dendrites often resemble organic matter they're actually crystal formations with a 'branching form'. These types of crystals are similar to what can be seen on glass windows during icy cold winter months.
Dendritic inclusions can vary in size from a tiny spot to the point where the stone is almost completely black.
When used for its metaphysical properties rhodonite is associated with the heart chakra. By removing blockages it can allow energy to flow freely enabling emotional wounds and scars from the past to heal. Rhodonite offers support during times of need and can be a great companion for when dealing with difficult and emotional situations.
