Thank you for submitting your items for appraisal. This appears to be a pair of lamps made from ceramic vases by Amphora-Werke Riessner, Stellmacher & Kessel, Turn-Teplitz . Not being able to look at the unterside, this can only be a very strong attribution. There were a couple of other manufacturers in Bohemia working in this style. The estimate is based on similar items sold at auction. "Asking prices" in the trade can be higher and vary.
