Antique Filigree 4-panel Bent Slag Glass Table Lamp. Nice

This is a beautiful vintage lamp with four highly detailed oriental filigree slag glass panels (amber & cream). Which was passed down from her great grandmother. I have no idea when it was crafted or from where. There does appear to be an Asian stamp under the lamp’s base but I wasn’t able to get a clear picture of it. The lamp’s approximate height is 15″, base 15″ diameter, shade 21 diameter. Each shade panel is 5-1/4, and weight is 6 lbs. Thanks for looking and feel free to contact me with any questions and I will do my best to answer them!
