Years ago I found this green chunk of crystal like material. I've been using it as a paperweight all these years. It measures approximately three inches by two inches.

I live in the central part of the San Joaquin Valley of California. Just north of my location there have been fossils found of many large prehistoric creatures. A center has opened called the Chowchilla (Madera County) Fossil Discovery Center. The location at which I found this specimen was in somewhat sandy soil that had been excavated for housing, roads, etc.

Definitely looks like glass. The strong conchoidal fracture and amorphous rounded form is almost a dead giveaway.

Wasn't sure this one went through. Looks like the product of a volcanic eruption, which might have also caused an extinction and lots of fossils. Search out some Helenite which was found after Mt St Helens eruption.

Dear Members,

Thanks for all of your answers. I stopped in to a jeweler today and he says it's just glass. Don't know why a chunk of green glass was there, but I guess the mystery is solved.
