Jade and Jadeite Identification

Jade, a symbol of purity and moral integrity, has been cherished across cultures for its beauty and durability. Comprising two distinct minerals, nephrite and jadeite, with jadeite being the more prized variety, jade exhibits a wide range of colors from green to lavender, red, yellow, white, and black. Its allure lies not just in its aesthetic appeal but also in its cultural significance, representing nobility, perfection, and immortality in various civilizations.
