These pretty tumbles are Madagascar rhodonite tumbles.
Rhodonite comes in pink, red, black, gray, yellow and brown, usually a combination of pink or red with black.
These particular tumbles have a vitreous luster with a pleasing mix of black, pink and translucent white hues. Rhodonite is known for its signature black and pink coloring, with pinks sometimes taking on a deep magenta-red hue. Some stones look nearly all black with hints of pink rhodonite.
The black inclusions often seen in rhodonite consist of manganese oxide and usually come in the shape of veins, spots, and or dendritic branches.
Rhodonite is aligned with both the heart and root chakra and it symbolizes a synergy of love and protection, passionate, strength, emotional balance, and cultivation of inner gifts. This stone represents the attraction of love and the grounding of negative energies.
Rhodonite derives it name from the Greek word, rhodos, which means "rosy" or "rose-colored."
