It has been revered for its beauty for centuries, and has been said to evoke wisdom, learning, and spiritual truth. Many say it correlated to the third eye and throat chakra, allowing for fuller understanding of one's self. The Sapphire Geode Mega Bath Bomb is absolutely stunning alone, but in a bath it is a truly royal experience. Simply drop it in warm bath water to watch rich waves of blue emerge in your tub accompanied by fragrance notes of gin, rosewater and cucumber. Each Geode Mega Bath Bomb is hand decorated with natural mineral pigments, mica, and sea salt so you can feel good about using it in your bath.
