This striking Ruby Kyanite tumble stone featuring deep red to brown hues is reminiscent of the fierce rhythm of a heartbeat echoing through the silence of the soul. This stone is a metamorphic rock (gneiss) where Kyanite and Ruby are major minerals. Tumble stones can be carried in the wallet, pocket or purse. Ruby in kyanite offers dual benefits to the wearer- ruby stimulates the heart chakra to promote love, passion, and vitality, while kyanite enhances communication, provides stress relief and grounding.
