Super sturdy heavy marble base - 30 pounds or so. The lamp does not wobble from the base, which was my concern before purchasing. The shade looks good from afar, but up close, the seams are very noticeable and not put together with great care and very .  

Pros: Super sturdy base. Nice lines. Appears more expensive than it was.
Cons: Shade not as nice as the rest of the lamp. Seam is very noticeable and not lined up perfectly.
