I have been told by many Peltier collectors at shows and chats that a zebra does not require aventurine. I have sold and seen for sale white base with black,or red,or blue, or green zebras.
What is the requirements for a Peltier Zebra ?
I myself have only seen any live zebra as white with black stripes. I agree the only Zebra that I ever collected were white base with black stripes with aventurine. But many collectors collect them with no av and different colors.
