It looks a little like the shape of a mushroom. The base does not light up however, this is an unusual Tiffany style lamp and very cute. Very well made. Colors are beautiful. I noticed when I was looking at this lamp online that the base and top did not really match. Now that I have the lamp in front of me it doesn’t matter. I love the base and the colors do not clash. The lamp appears to be well made and sturdy. I looked at well over 100 Tiffany style lamps and when my son saw this one he loved it. So this was a surprise purchase I made for him. His feedback to me was it looks so much more beautiful in person and asked if he could keep it in his room. For a 20 year old boy that is huge. We are moving and this lamp will go in his room. The base is green with dragonflies, leafs and son flowrrs done very nice. There is no green in the shade.
I like this lamp a lot. For the price the quality and workmanship can’t be beat.
