This is a natural piece of boulder matrix. The opal is embedded in the ironstone and it takes a good polish. Some times this material has very fine fractures in it which you only find when you go to rub it down. For this reason we tumble the material to make it solid.

Quilpie Boulder Opal formed millions of years ago as silica-rich solutions gradually filled tiny cracks, cavities and spaces within ironstone and surrounding rock.
