Clear Cut Crystal 1920's Candle Lamps

This pair of 6.5 cut crystal candle lamps are identical to a set I saw online that were removed from a 1920's apartment building in New York City that was being remodeled. Despite my extensive research, this is the only information I could find. The other listing had no other details about the shades except where he found them. It appears they sat on a round ledge of a candelier as each has an inch round hole at the base for the candle or more modern light bulb. I wish I had more to share of their origin but they are stunning.

Please Note: Before I list an item for sale, I do extensive research to identify its origin, pattern, date manufactured, and authenticity. I also inspect each item very closely and disclose any imperfections I see, but my items are mostly vintage, gently used pieces, and there may be a flaw I missed or even a mistaken pattern name or manufacturer given. I never purposely intend to mislead, but I’m not perfect so please look very closely at all the photographs
