Apophyllite is a group of minerals, primarily a potassium-calcium silicate, known for its clarity and often glassy appearance. It is often found in volcanic rocks and can come in colors like clear, white, green, yellow, or pink. While it is a mineralogical group, the name is frequently used in crystal healing contexts to refer to crystals believed to enhance intuition and spiritual connection, and its name is derived from the Greek word for “flakes off” due to its flaking property when heated. Green apophyllite is believed to offer benefits related to emotional healing, inner peace and grounding.
