"Welcome to Marble Connection" I moved your posts knowing you'll get more of a response here in "General Marble Glass Chat" I keep forgetting to hit the save button

Vacor de Mexico makes many types of Frit marbles also, yes hard to tell the different manufacturers apart, some very valuable, others worth pennies. https://www.billes-en-tete.com/liste_billes.php?lang=en

"Welcomer to Marble Connection" I moved your post to "General Marble Glass Chat" because I feel you will get a quicker and more accurate response here. The answer to your question is kind of a mixture, it has taken me years and I'm still learning as new providence is revealed we all learn. Colors, seams, size along W many other traits all play a part in marble identification. There will be other's that chime in to give you an idea, if you have any pix please post them, they can be very helpful as you start your marble journey. Again "Welcome"

The one on the R is a Champion Red Cloud

Peltier Zebra, yes that is a seam

Here's his site : I don't see he makes that oner anymore, measurements and an Email or phone call to him might do the trick https://salazarglass.com/

"Welcome to Marble Connection" Vacor serpent IMO

A Great Basin Bristlecone pine

Amber swirl IMO

IF the OP is semi transparent Blue it's a Blue Panda

"Welcome to Marble Connection" Bennington, fired and glazed clay marble, probably came from Mexico, yes it is old. Others will chime in W more info, I believe yours is called a fancy Bennington because of the mottled coloration.

Try a 5000 K daylight bulb, low wattage 15 if you can find it but 20w is ok, macro setting if you have it, the av should show then, try a neutral background, I found grey felt most effective, so the camera focusers on the marble not the background. A little tweaking and you'll have it perfected
