Its hard to tell from the picture as its too blurry. Did you polish it, or was that its natural shape. Can you also ascertain that its not a green piece of polished glass?

It looks like beach polished glass.

It's not polished glass this stone is too thick to be glass... It doesn't look like glass, it doesn't feel like glass, it doesn't vs puns like glass, it Doesn't have any sharp edge wich means it can't break as easily. This is originally how I found it.. Here is a better photo

Thanks for the better photo. It doesn't looks like any natural mineral I can think of. It definitely looks round and waterworn - which could be an effect that water can have on glass to smooth it. Were there any similar pieces in the area? Any way you can test its hardness?

After living in the Pacific for the past nine years i have come across many many ocean worn and rounded glass pieces. they can vary from being slate thin smooth flat pieces, to being more rounded and sometimes having a thickness of a mans thumb depending on the original object's design, shape, and how it fractured off the original object. They develop many tiny pits in the surface due to the constant rolling, sliding, and tumbling on the coarse ocean sands as can be seen in the second picture provided. so due to experience and what i see in the picture i'll say sea glass. btw it does take many many years for the glass to be smoothened and pitted like the one piece you have. who knows? maybe it came from an ancient ship a few miles away or that passed through there years ago :)

Also the "stone" has a gritty feel does it not?
