Limonite, also known as brown iron ore in Japanese, is characterized by its vibrant red, membranous inclusions within quartz. The reason for the membranous inclusions is that iron components enter the cracks in the quartz after its formation. Due to this appearance, it is sometimes called natural aurora quartz or aura quartz. If there are few cracks, the membrane will not be very large, and if there are too many cracks, the transparency will decrease, so high-quality specimens are traded at very high prices. This is a large bead of Limonite in Quartz where the red color is clearly visible. Although there is some cloudiness, the inclusions are more than enough to make it a lustrous piece.
