Opal
description: <p style="text-align: justify;">LOCALITY: Mintabie, South Australia (state), Australia <br /><br />7" across <br /><br />This opal on sandstone specimen glows bright red when exposed to an incandescent light - since this type of light is rich in red wavelengths. It is a large, flashy and decorative piece although it contains little cutting rough.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">This piece was bought in 2014 from Michael Larrett of Adelaide, South Australia.  I traded it out to Robert Sielecki in 2015.  He then sold it to "The South Australian Museum", Adelaide.  </p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">Photo by Matthew Webb of Melbourne, Victoria, Australia </p>
