Thank you for submitting your item for appraisal. This appears to be an american stained glass table lamp of the early 20th century. The cast metal oval lamp base is decorated with anemone in relief, the shaft is decorated with floral ornaments surrounding a young girls head in the art nouveau style. The lamp base shows a production or foundry number "125.5" but not a foundry name unfortunately. The flower and foliage decorated lamp shade appears to be of the same period. The estimate is based on comparable table lamps sold at auction recently. There is no measurement for the sentimental value you might attach to the item.
