These lovely vintage cranberry glass tumblers are in a diamond optic pattern. I'm not sure of the maker, since similar tumblers were made by several different manufacturers. It's likely that some of these came from different makers. I have five of these gorgeous tumblers available, the price is for one (undamaged), but I would be happy to provide a discounted price for more than one. The two that have issues will also be discounted if purchased separately.
They are 3 1/2 inches tall and about 2 7/8 inches in diameter. Condition on three of them is excellent - no chips, cracks or other issues (these are the three to the right in the first picture). One of them has some black inclusions that happened in manufacturing (see the picture). It also has two very tiny fleabite chips to the rim. These are very small and could probably be buffed out. The fifth one is pictured separately. It has a fairly significant chip out of the rim as is shown in the picture.
I will also be listing some inverted thumbprint tumblers that I got from the same estate.
