Is this lightening sand?

[digger460]

Buddy of mine gave me this the other day. He told me he was told it could be lightening sand. Supposedly what happens to sand when hit by lightening.

It was found in Kankakee county in Illinois, and in sand.

Any thoughts?

It does not appear to be a fulgerite, your lightning sand. Fulgerite's take a number of forms and have a glassy/melted appearance. In sand they often have the shape of lighting, dentritic, and you can see the sand fussed into the glass they are formed in. I'm not ruling it out but your specimen seems more like a nodule of something else.

Thanks DD. From the pictures I had seen, it didn't look like the specimen. Thanks again

Agree with DD...this looks like a calcite nodule

The pics are a little blurry, when I look at it, I am thinking it looks like a stream worn milky quartz cluster. If it is calcite instead, a quick test with vinegar or will decide that. If no bubbling, try a hardness test?
