Green Mica Bridge Lampshades are a Craftsman era design. The natural organic appearance displays flecks of green, gold and brown. For extra pop, these bridge lampshades, are bordered with a nut-brown braided trim. The braid displays a faux leather appearance. A semi-transparent outward glow is produced when lit. Yet the downward light for task lighting is bright.

The shade was expensive but looks really nice on the antique base. It was tricky to get all the parts together. Instructions on the web site and one other we found were helpful. I would do it again on another old lamp.
