Valued across East Asian, Mesoamerican, and Maori cultures for thousands of years, jade is both a cultural and a gemological term covering two distinct minerals, jadeite, a pyroxene, and nephrite, an amphibole. Both are treasured for toughness, beauty, and spiritual meaning: jadeite yields the vivid imperial green and lavender hues prized in Chinese and Burmese tradition, while nephrite ranges from creamy mutton-fat white to deep spinach green, long important to Chinese and New Zealand Maori carvers. Crystallizing in the monoclinic system, jade measures 6.0 to 7.0 on the Mohs scale, and its exceptional toughness suits intricate carving. Semi-precious and moderately priced as a broad category, its finest imperial jadeite can command prices rivaling fine diamonds.
