Hi Caprice,

Thank you for contacting Mearto with your appraisal inquiry.
Is this signed or marked Kreiss anywhere? They made quality lamps but typically marked their pieces but I can't see one in the photos and have appraised it as if it were NOT by them. The value will increase a bit if they are so please let me know how and where they are marked and I'll update this appraisal.
Based on the photos and information provided, and subject to examination, this is:

A Renaissance Revival style marble floor lamp
American, mid 20th Century
Surmounted by a variegated art glass bowl-form shade, raised on a lobed marble shaft, on a bronze tripod foot on marble base.
69 inches overall height, base 14 inches wide.
CONDITION: appears to be in good condition. Not guaranteed as to working condition
$600-900*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, and thank you again for using Mearto.
