Upgrade your existing lighting or add a distinctive finishing touch to any table lamp with a designer lamp finial. Crafted from a stunning, gold electroplated picture jasper slice on a knurled brass swivel base. Handmade in Wisconsin. Meticulously prong-set and fixed with jeweler's-grade adhesives. The brass tone finial base will fit a standard-size lamp harp with a 1/4" stem. Coloration will vary based on the nature of the mineral material and varied light sources. Sizes vary up to 1/2" due to the natural diversity among mineral specimens.
