Grandidierite’s energetic signature is not dissimilar to that of amazonite – if you imagine amazonite on steroids. Like amazonite, it is uplifting, balancing, and aids communication, but the communication aspect is strongly emphasised. Also like amazonite, it is good for leadership, but is much more forthright, making it useful for public speaking, especially if trying to get the attention, or change the viewpoint, of the audience. Grandidierite demands justice and speaks with a positive voice. Physically, it improves and supports the lymphatic system and aids inner strength.
