This type of marble has not been posted in quite awhile.
A Peltier “Pearlized” Patch—very rare.
@ 5/8” these will come with a small variety of base colors—blueish—grayish—whitish—brownish always with the green pearl patch as far as I can determine—this combo that I posted was always my favorite color combo.
I am afraid that folks are losing track of what once was a highly desired find, If I could afford it—enough said.
The stress cracks in the one that I display are common—just a matter of patch glass cooling vs base glass cooling.
Peltier did not make many of these probably due to production problems as I describe above.
I hope to see some more history of these rare marbles posted as they need some more recognition lately at least.
Marble—On!!
