I found this partially embedded (most was exposed) in the ground at a city park in Forest Park, Ga. one day when I was younger. I kept it for over 18 years now just because I thought it was really unique. It's glassy looking and is a bit translucent, with a olive green hue when led light passes through it. It has squarish looking inclusions that are mainly a frosty light blue and rusty reddish brown, mainly on one side. I thought of two possibilities, either slag glass or tektite. Any ideas as to what it may be? I do know Georgia has been known for tektites. Also, it weighs 82.8 grams and is roughly 2" in width and length and 1.5" height at the longest points of it.
