Can any ID this please?

G'day rock lovers. I have a bit of a collection going in my cabinet. Aqua, apatite, garnets, sapphire, quartz, fire opal, kyanite, citrine and other bits and pieces. I'm always looking at rocks while I'm out bush and bringing home things like jasper and other interesting looking things. Anyway I picked up this stuff and gave it a bit of a go I'm the tumbler. I have no idea what it is, any help with identification will be appreciated. Cheers

Is it translucent? Looks a bit like some kind of potch from where I'm looking at it.

Im with Lefty.... Potch Opal..... Not quite Opal...

Yes translucent. I was thinking potch. Cheers for the confirmation blokes.

No worries - though I probably would say "suspected" rather than confirmed at tthis stage.

Maybe re-post it in the mineral identkfication thread where Goldirocks will see it.
