Commentaar:
A colourless variety of Opal. Hyalite is opal-AN, an amorphous silica-glass containing about 3-8% water.
Hyalite is quite often present as a coating almost invisible to the naked eye on quartz, feldspar, topaz, black tourmaline, aquamarine etc. falsely suggesting that these minerals fluoresce.
