Buy Vintage Lamps ❲100% HIGH-QUALITY❳

Quality vintage lamps usually have heavy cast-iron or weighted bases. If it feels like light, flimsy plastic, it might be a modern reproduction.

Check the underside of the base or the interior of the shade for maker’s marks (e.g., "Artemide," "Sonneman," or "Underwriters Laboratories" stickers).

1stDibs and Chairish are great for authenticated designer pieces.
