    The title "fire" opal that I used was in reference to the white opaque opal with the gold looking flecks that reflect a lot of light when the stone is formed and polished into a cab. The more flecks in the stone equalled more "fire"; and the higher the quality. The name had nothing to do with HOW the opal was formed. That experience I had was in Vietnam at an on base hobby shop where the person running the place helped us. He said the reflecting flecks gave the opal the look of internal fire and that was how it got it's name.

    Shortstack,
    Fire does refer to the display of colour.
    However fire opal does refer to a reddish to orange body tone. Google it.
    Fire opal mainly comes from Ethopia, Mexico and a few other places.

    That's the experience I have while studying gemmology.
    Geologists are gneiss, tuff, and a little wacke.

    Re: Opal

    The Mrs. and I LOVE going opal hunting....We have some very nice ones as well. The only problem with some of them is that they are still "wet" opals, and only good for specimens. Virgin Valley Nevada is where we go and we love the blacks the most, but they are a bit harder to find of course.
    Beautiful stones you have there!

    Whatever it is, it is valuable. If nothing else for the lesson learned or simply the experience of having been there.

    Re: Opal

    Some nice pics on this post, I am an opal lover myself, the nearest opal fields for me are a 10 hour drive away, but I am going next year for sure! Didn't know Ms Peach was into rocks?
    Just one more hole...Then I'll go home!

    Ozzy,
    Sounds awesome! I would love to see the opal fields myself some day.
    Don't forget the camera.

    Re: Opal

    I believe fire opals are also found in Arizona.
    Here on the left coast we have 'Opal Mountain' just north of the town of Hinkley, which is just west of Barstow. Unfortunately, there are no fire opals to be found there though opals of other solid colors have been collected there for years by rock hounds.

    Re: Opal

    am beginning to love opals myself. I have a friend here near me in Fl that owns a BO mine in Koroit Opal fields in Australia, its near Cunnamulla or somewhere near there. I traded him a large amount of my coral for some of this, some of these killer pieces are his to show me what it looks like.I have made a few cabs so far and here they are. My shop looks like I have been mud slinging

    Re: Opal

    the reefs I dig on arent on any charts or waterway, they are on land, I dig these from a freinds property in a county that was a huge coral reef bed when Fl was under water, these are silicified. I`m a 5th generation Floridian and know where alot of different spots for rocks are . Could care less about the reefs out in the ocean, its way too crowded out there for me.
    I find alot of coral in the rivers also, beautiful stuff.
    Heres my coral , polyped and pinhead

    Re: Opal

    your opal looks good, I`m having a heck of a time working that small stuff. Alot of the opal on the BO is small or I find a layer of that hematite on top and takes for ever to grind down to that thin layer of it.

    Re: Opal

    I actually was taught cutting small pieces, so I have little problem with those.

    Re: Opal

    Here's a pic of some nice synthetic Gilson opal I found at a swap meet for $0.50!
    I cut it and put it into a ring I made.
