How do I tell if a Bertoia Diamond chair is real?

To tell if a Bertoia Diamond chair is real, examine its details closely. First, look at the corners of the backrest on the wire frame. An authentic chair will have gently rounded corners, so sharp points or rough areas may indicate a replica. Next, measure the dowels that form the base. Genuine chairs have dowels that are exactly 0.5 inches in diameter. Reproductions tend to feature significantly thicker dowels. If you're still uncertain about authenticity, a certified appraiser or knowledgeable antique dealer can assist you. Find a collection of Bertoia Diamond chairs on 1stDibs.
