How can you tell if David Yurman is authentic?

To tell if David Yurman is authentic, first look for the luxury jewelry maker's marking. Authentic pieces will feature a D. Yurman, DY or David Yurman stamp, a copyright symbol and hallmarks that identify precious metals. The stamp should be crisp and clear, with numbers and letters evenly spaced. Also, carefully examine the jewelry up close. If you see cracks or flaws in gemstones, glue or soldering marks or other imperfections, the piece is unlikely to be genuine. If you need assistance authenticating a particular piece, seek the help of an expert, such as a certified appraiser. On 1stDibs, shop a selection of David Yurman jewelry.
