Looks like a silicate. Chalcedony? Common opal? Hard to tell. I suggest a hardness test with a known piece of quartz.
Opal is soft, easily scratched, chalcedony is not.

Considering where you found it I'll side with chalcedony and what appears to be on the border of a jasper rind.... almost an agate. As EU points out opal is soft, test the clear areas with a bit of quartz~ chalcedony wont scratch easily but opal will. Let us know.
