This lamp weighs about 23 lbs. but feels heavier. It has a solid glass base. If I could have given this lamp 10 stars, I would have. It was packaged very secure and of course very easy to put together. The picture doesn't do this lamp justice. Also, we saw the same lamp at Restoration Hardware, a new store on Dawsonville Georgia and this lamp had a price tag of $500 on it. No joke!!!!  You could use this lamp in so many places, it's just simply beautiful.
