White & green glass rock ?

[Nightowl 280]

I was at a estate sale to day and saw a rock that didnt fit the landscape of florida . So i picked it up and paid a buck for it . Im wondering if anyone can give me a idea if its a rock or something else and/or idea of what it may be .

9"x4"x6" slab of green white glassy rock .

looks like opalite

i think the over head lights may be playing tricks on the look of the reflections on this . The blue looks more like a old agate marble then a opal or opalite

I would say opalite, would make some nice jewelery.
