Treated Opal. Also called Sandstone matrix or Fairy opal. It starts out with a light brown sandstone colour but this it is cooked and burned and then this brings out the colour.  I love it in beads. This is Queensland opal. It is different to Andamooka opal treatment which is acid and sugar treated.
