How can I tell real jade from fake?

One way to tell if jade is real or fake is to scratch it in an inconspicuous area with a needle or a knife. Authentic jade is unlikely to scratch, while a clear mark will usually form on fakes. The only way to know for sure if a piece is real jade is to have it examined by a licensed appraiser. Shop a range of expertly vetted jade jewelry and decorative objects on 1stDibs.
