A lot of manufacturers these days make Tiffany peacock lamp reproductions. These don’t cost more than a hundred dollars. But there are a few who try to pass off a reproduction or a replica as an authentic Tiffany peacock lamp. Everything from the stained glass to the patina on the base is recreated to perfection.
One of the easiest ways to spot a fake is to gently tap on the glass of the lampshade. It should rattle, like its loosely fitted. Reproductions usually have a firm lampshade that seems rigid to the touch.
You can even observe the glass closely for tiny speckles of color, which are called Confetti glass, a sign of an original. If you are still unsure, pay an appraiser to authenticate the lamp.
