Modern gemologists use the word “jade” as a generic term for two distinct mineral aggregates – nephrite and jadeite. Soft enough to carve, tough enough to withstand repeated hammer blows, the two minerals look and feel very similar. But their chemical compositions are different, and gemologists classify them as separate species.
Jadeite’s most desirable intense green can be worth millions. This necklace, the Doubly Fortunate, sold for $9.3 million at auction.
