The paperwork that accompanied the lamp says it was manufactured for Plow&Hearth, which partly explains why the lamp base is lightweight and may be resin. The 3 support arms that the tiffany style glass shade sits on are metal. The lamp came well protected for shipment and arrived intact. Assembly was a breeze, only needing to position the glass shade atop the already assembled lamp base and arms. The lamp sits low like I want to preserve my ocean view, while looking beautiful. I removed 1 star for the unexpected, apparent resin lamp base.
