How to Identify Jade
Jade (nephrite or jadeite) is defined by toughness, not hardness: its interlocking fibrous structure means it will not shatter under a hammer blow the way most green rocks do. It feels dense and cool, takes a greasy-to-waxy polish, and rings when tapped. Serpentine is the common impostor — it scratches easily with a knife, while jade resists.
