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.

About Jade

O jade é um termo que se aplica a duas pedras distintas: a jadeíte e a nefrite. O jade tem sido venerado por milénios em muitas culturas, especialmente na China, Mesoamérica e Nova Zelândia, onde tem importância cultural, espiritual e artística profunda. O jade imperial — jadeíte verde intenso semitransparente — é o mais valioso. A nefrite, mais comum, tem uma textura fibrosa que lhe confere resistência excecional. O verde é a cor mais clássica, mas o jade ocorre em muitas cores.
