Lava Rock Diffuser OilThe Scent: This warm and earthy fragrance is inspired by the history of Hawaii that is inexorably intertwined with the volcanoes and lava. The Inspiration: The Big Island of Hawaii is home to Volcanoes National Park established in 1916. The Park displays the results of 70 million years of volcanism, migration, and evolution processes that thrust a bare land from the sea and clothed it with complex and unique ecosystems and a distinct human culture.
