precious gems ...

jono and i have been having an ongoing discussion about opals
at the museum the other day we saw a display on precious gems
this furthered our discussion but this time i was able to point to the display as i explained
and then on the way to the train station we saw an opal dealer
and we talked again about the stones in the window

this morning he came running in from the back patio
asking if i thought this could be an opal

he found it in the back yard ...
