Hyalite Opal

Hyalite Opal is a transparent to translucent form of common opal that forms as a secondary mineral in volcanic cavities, developing botryoidal or globular coatings from low-temperature, silica-rich fluids and containing 3–8% water. It lacks play-of-color but is valued for its glassy appearance and occasional green UV fluorescence caused by trace uranium.

Energetically, it is associated with clarity, emotional purification, adaptability, and subtle perception, supporting intuitive awareness and inner light during periods of transition.
