I'm confused.

Its actually chromed stainless steel by artist Zhan Wang.

Why is this in a marble-specific forum?

How did you identify it specifically as that?

Its not glass.

Yes

As others noted - a caliper. Use fractions please.

Run away from that seller. I DO love how all photos are mysteriously out-of-focus. And NO returns. Whats not to like!

Machine made with crud in the glass. No "Lutz". If you look for "Lutz" etc - you'll find it in places that it isn't.

Looks like a normal bead shoved into an optic mold device. Anyone can make a clone of it tomorrow. My first torch experience was in a Kate Fowle bead class.

I've seen plenty of people who think they do. Right here, no less. (Cue the $3,000 Vacor)

I think they're more like a smoking candle wick....

Steph is correct - no consumer had UV lights in the vintage days. It was about the glass having just a bit of a different look in sunlight. These were penny kids toys. It wasn't rocket science.

Coreless swirl. All cane-cut marbles have an initial gather. Period. People have come to refer to the absence of color or construction as things like "ghost" - which doesn't make any sense. When an initial gather is marvered, it will have some texture or pick up some frit dust etc etc. But that doesn't make it a core deserving of a name, absent some intentional construction that merits it.

Looks decidedly modern to me. Remember: Most fakes usually have a big story that comes with them in order to remove suspicion and hesitation. This one comes with a very big story. The bigger the story - the bigger the inflation. Cheesy fakes usually come with a big price too. Some people can't resist the bait.

Put me down for Jabo.

Think of doing the Florida show.

Its a Master. It isn't jumping out at me as anything more exceptional than some other Masters that come along regularly, even if intact.

On the bright side - you can display it without a marble stand!

Its not old.

Thats new glass.

It is vintage.

Yes - all modern fakes.
