Not sure how many Cairo have been found in this size but it's the first one I've seen so far and it's a big one too! I would lean towards a more rare classification here in terms of size. Translucent Purple Glass when backlit. This one wasn't named, but should have been. It's very similar to the Heaton Blackberry Swirl.. I'm kind of digging the Cairo version more though.. The swirls are sharp and defined and the glass more like dark grape juice! No damage on this one. Some silvering and very small asmade flat spots
