Wow!!!!!!

Mica is a mineral that was used, and is still used today, for its shiny and reflective properties. Especially in ancient times, it was included in marbles to create a shiny and bright effect You can find it in clear transparent marbles, in various shades of blue (aquamarine, cobalt, etc.), in green, amber, and more rarely in yellow and red.

This Bulgarian shouldn't be very recent. A single pontil, "German" cloud

Fritz Lauenstein- 2,047 (52mm) These earthy colors, the first one reminds me a lot of a handmade German Made in the early 90s

I agree Here is a reproduction by Kelly Schmidt, He makes them very well
-
Nice box, there are some very crowded ones there
-
I don't see mica

Correct, but this marble is curious, as it has been transformed/distorted by the former marble worker 'Rich Shelby' 🙂

I agree. About a month or two? A sulfide (as above) with green glass was hammered at auction for $3000... insane! But it is pleasant and tranquilizer if you can see it as an investment, and I think these are. Obviously, with these prized marbles, there could be an equally high risk of replication, and here, you need to be cautious when purchasing.

Do you know what it's about? Aside from the fact that he is German..

Yes, to this black aspect due to the strong yellow coverage, but when exposed to light it shows a beautiful blue with greenish tones, precisely because of this yellow coverage. A kind of refraction

I found another red one

I like this. A "species" of gooseberry with a divided core. Polished

Yes, indeed the yellow is very light, in mine, almost irrelevant, but the patch is great
