Pink Rhodonite, a manganese spar, has different compositions depending its amount of iron, magnesium and calcium. It contains often dark green, almost black, manganese oxide dendrite and is an uncommon gemstone. Rhodonite is known as the emotional healing stone and belongs to the heart chakra.
Rose-red rhodochrosite, another manganese spar, has white stripes and a glassy shine. It is softer than rhodonite and is sometimes a by-product of copper and silver mines. Rhodochrosite also exists in brown, yellow and grey colours. It is the stone of unconditional love and compassion, but also a stone of playfulness and joy that gives you confidence in yourself.
