This is a special type of opal which is often classified with common opal. Hyalite is, however, a very distinctive material. It is always colourless and glass clear, and contains less water than other forms of opal. Its water content is usually of the order of 3-4%. Hyalite is most commonly found in association with volcanic rocks, especially in small cavities, or vugs. It may also be found coating secondary minerals in the weathering zone of ore deposits.
