Russian Hexagonal Green Glass Water Goblets

Beautiful pair of antique Russian hexagonal water goblets most likely from the 19th century. They are signed although I cannot read Russian so do not know what it says. They also have the Russian double eagle marking. I did see the identical goblet (with the exception that those had gold detail) online listed as Fedorovsky Brothers Glass Factory in Sudogda, Russia. And also an identical looking (except for color) set of six goblets listed as Russian Uranium Glass goblets, Maltsov. This pair is not the yellow color of uranium glass or vaseline glass which glows green under a black light but that wonderful shade of green all the time. They have a great heft and feel and are in wonderful antique condition with the exception of a small chip on the underside of the foot of one of the goblets and a possible minute hairline crack to that same goblet at the foot. (See photo) This pair came from an estate where the grandfather, the original owner, was the Chief Medical Officer in the Panama Canal during the first half of the 20th century where and when these were obtained. I’m told they entertained young Eisenhower so possibly Ike sipped from one of these goblets! Whether or not, they are beautiful and it’s a good story!
