Where can i identify a gem i found here in florida

Question

I live in florida and I found a gem...

It's appearance are as follows...

It's very dense, but a sure blue color...

it has a volcanic look because you can see small gass crators on it, it also has ash on it, the color of light-grey... both the ash on it and the other side have gas bubbles on the sides...

there is, however, a piece of a chip of it from a crack that shows it's very light colored in a thin layer...

here are some stones with resembling gass hole things...

Answer 1

It looks like Peridot.  Peridot is a volcanic crystalline.

It is not emerald because an emerald is a metamorphic rock with hexigonal crystal habbits.

Answer 2

It is close to impossible to make any sort of identification without even a picture of the item let alone seeing it for real. However your description sounds exactly like what one would expect from blue glass that has been fused in a fire of some sort and not a gem at all.

Take it to a local university, rock shop or even a reliable jeweller to get an opinion but do not get your hopes up too high.

Hope that helps a little.
