Great thread. I have never seen a peltier black banana in an original bag. The closest one i've seen is this one posted at joemarbles.com, and it appears a shade of lavender? Maybe one has been found at the peltier site?
Ima_ddicted, i would love to see photos of the cats with aventurine.
This one is a clear brown banana that i believe is peltier but not found in an original bag.
I believe Chad's cats eye to be a master. Here is a bag i recently opened of master cats eyes (apologies to the bag enthusiasts).
These 7 black/purple cats were inside. Of the 7, 4 have peltier like banana veins, some with bubbles and some without.
This is a close up of the bubbly one.
This group of black/purple cats were also pulled from original master glass bags. Some have champagne glass, some light blue glass.
