As far as I can tell, a nice bunch of Imperial types from Asia. It sorta looks like oxblood on the blue one and be sure to check for AV on the green ones - it's not too uncommon.

Thanks Joep - any idea when they were produced?

Thanks for the lead, Alan - what talent, her work is amazing. I especially like the Christmas cookies.

Most of the white-based ones are lined China marbles made in Germany and the blue ones are called Benningtons, also from Germany. The small bluish one is dyed clay, which I think were made in a few different countries including Mexico, Germany and the USA. The one with the spiral pattern is probably the least common.

It's crazy how tiny those facets can be on the best examples.

Nice Burnt Christmas Tree!

I really like Vitros. The Aquamarines (first marble) are very nice marbles and I think your second one is great too.

I agree with Steph that there is a very good chance that agate is German. The way I check for hand-faceting is to shine a bright light on the marble and look at the small reflection it makes, i.e., the little dot of bright light on the surface of the marble. Then rotate the marble slowly and see if the that little bright spot jumps around or moves smoothly across the surface of the mib. The light spot will appear to wiggle around if the marble is hand-faceted. For comparison, you can do the same using a machine-made glass marble and you will see how the reflection moves smoothly if there are no facets.

Try "glass candy" - Murano did these . . .

I have seen similar marbles. As far as I know, they are a fairly modern attempt to reproduce antique Benningtons. The colors tend to give them away, although I have seen wishful-thinking people pay a premium for them thinking they are authentic.

Nice Agate. It looks like it's probably hand-faceted. Do you know how to tell whether it is or not?

The blue has me thinking Ravenswood.

That is very cool - I don't think I've ever seen a similar one. It really looks great mounted and lit up!

A really nice assortment - what a great gift. The sparklers are great!

Well, those are cool - very creative, and it's surprising that you can even ID them. I'll bet your kitties would have a blast with that bowl-full. 🙂

It's a nice marble, and 3/4" is a good size for a transparent swirl. At that size, it's probably not Ravenswood or Heaton - I'm leaning Champion.

Champion is my bet.

The OP is a Multicolor Rainbo. I think it's just the pattern that determines MCS vs MCR - no swirl to the MCR, pretty straight seams and ribbons.

What a bunch - the "bullet molds" are crazy cool.

Great collection, Joep!

Those without fractures are HTF and even with small fractures they are still very nice Alleys.

The first two look newer to me - maybe JABO, but not sure. The third is a Peltier Multicolor.

I agree it has a bit of a Champion NOF look but I also wonder about Vacor . . .

Even some patches show feathering . . .

Yup, last one is an Alley Superman - nice marble. Many have fractures, usually in the yellow. If yours doesn't, that's a big plus.
