What is this???

(confirmed to be genuine quartz by using a polariscope)

[Bob Harman]

While I like your other examples, could this most recent example be a small piece of man created metal included into a polished piece of lab grown quartz or just a small piece of polished glass. If so, there would be nothing natural about it??? BOB

[alfredo]

He did say he had used a polariscope and confirmed it was crystalline, so it isn't glass. But, yes, Bob, it does look synthetic. Could be lab-grown quartz around a piece of metal. I have lab-grown quartz with metal wires inside.

[zbhjzm]

Well, I can only confirm that it is genuine quartz, there is simply no way to tell if it is natural or lab-grown. But, if it is lab-grown ,I guess they will make more ,so I'll see if I can find something like this in the future.
