Fifth Avenue 24% Lead Crystal Lampshade Made in Germany

This is a beautiful heavy lead crystal lamp shade made in Germany for Fifth Avenue Crystal LTD. It is probably for a fairy lamp or hurricane lamp, but I'm not sure. It measures 4 inches tall, 5.75 inches across the wides part and the top opening is 1.5 inches across. It is in excellent condition. It is a very nice thick heavy piece. I do not know the age, it is an auction item. It has the original label.
