What type of opal is this?

[micro]

I inherited this opal with no information to, it except it may have been found in the U.S. I have looked around the internet and I am not sure what catagory it fits in. I would like to be a bit informed before taking it to a jeweler to see if I want to make a piece of jewelry. Thanks!
