vintage Fenton ruby glass lampshade, quilted diamond pattern shade for student lamp

Vintage hand blown glass lamp shade, brilliant red color all the way through the glass. It's probably a Fenton shade, we think.

This measures 6 1/2" across the widest part of the shade, about 4 1/4" tall. The fitter measures 5 3/4" across, and the opening at the top is 3".

It's in excellent condition without chips or cracks, has just a little roughness left to the fitter edge from the manufacturing process.
