A big perfect mineral sphere Tiger Eye

[The Nickel Guy]

I would say this is about 1.6 inches or about 40 mm in diameter. It is so pretty, I don't want to scratch it with my calipers.

Very simple Tiger Eye I believe. Kind of reddish brown rather than the tan brown. Just awesome but tough to photograph.
Was in my latest score and I thought it was just a big glass red marble in the pictures.

The equator is more defined than my picture shows and seems to follow you if you hold it in front of your eyes and move your head from side to side.

Looks like mineral type, not machine made.

Ummmm,

This may just be a "Fiber Optic Marble" imho.

Yes--they are a thing to watch out for.

Marble--On!!

I have a purple one. They’re pretty cool. Mine is going into my Granddaughter’s stocking. It’s the same size as your’s🔥

You know, I just did a search for Fiber Optic Marble and found that they make these. Saw one that looked just like mine and was described as such and another like mine of course as rare mineral.

Even the ones that look more natural can be man made. The ones with the grain and tight cracks. I saw one broken and inside it looked like there was some kind of metal disc.

Well, I have had a big learning day! Thanks

LATE EDIT - Not that I don't like it as much as I did at first. It still is an impressive sphere. Still a keeper for me.
