Made with a pumice stone from the Azores. These stones come from undersea volcanoes and are the only ones that float making them very good for dowsing or divining. These are made by our son Kai. We will do our best to align the right stone to your energy for each order. Everything we use from nature we ask for the blessings and the permission to use it giving Mother Nature back a gift. Thank you so much for your support. Love and blessings.
