Hyalite Opal
The Radiant Glass of Inner Light
Also known as: Water Opal, Muller's Glass, Jalite
About the stone
Hyalite opal is a transparent, glassy variety of hydrated silica that forms rounded, bubble-like crusts and generally lacks precious opal’s rainbow play-of-color. Abraham Gottlob Werner named it in 1794 from the Greek hyalos, meaning “glass”; its historical name Müller’s glass honors its reported discoverer, Franz-Joseph Müller von Reichenstein. Other names include water opal and jalite, although “water opal” can also describe other transparent opals. Sources include Mexico, the Czech Republic, Hungary, Australia, and the United States. Many specimens fluoresce brilliant green under ultraviolet light because of trace uranium, inspiring the nickname electric opal for some Mexican material. Its lore is predominantly modern: crystal practitioners associate it with intuition, emotional clarity, and spiritual awareness.

Care and handling
Hyalite Opal contains water and a trace of uranyl, a residue of uranium. The radioactivity is described as very slight, but as a sensible precaution wash your hands after handling it, never grind, sand or cut it dry, avoid breathing any dust, and do not put it in water, elixirs or your mouth. Keep it away from children and pets, and store it in a closed container. Like all opals it dislikes sudden temperature changes, heat and very dry air; wipe it only with a soft damp cloth, and keep it out of long periods of direct sunlight.
Individual experiences with Hyalite Opal vary, and its effects are a matter of personal belief. Enjoy its glow responsibly, handle it with care, and use it mindfully as a gentle reminder of your own inner light.
