BulletPoint2 : Apophyllite can be a beautiful mineral, forming in lustrous, transparent crystals that are well-formed and occasionally very large. Though it is found worldwide in volcanic zeolite environments, the Indian traprock quarries have produced enormous quantities of this mineral in all different shapes, sizes, and colors, making Apophyllite easily obtainable and very affordable. BulletPoint3 : Apophyllite was originally regarded as a single mineral, with a variable ratio of fluorine to hydroxyl. In 1978, the IMA sub-classified into two distinct minerals: Fluorapophyllite and Hydroxyapophyllite. In 1981, an additional rare member with sodium replacing the potassium was added to the group, and called Natroapophyllite. BulletPoint4 : Apophyllite almost always occurs together with zeolites, especially in traprock environments. Apophyllite appears very similar to the zeolites, and is sometimes even confused with them. However, the physical structure of Apophyllite is different, with tetrahedrons aligning in sheets as a phyllosilicates, as opposed to the zeolites which are tectosilicates.
