Jade is an umbrella term for two different types of decorative stones used for jewelry or ornaments. Jade is often referred to by either of two different silicate mineral names: nephrite (a silicate of calcium and magnesium), or jadeite (a silicate of sodium and aluminum). Nephrite is typically green, although it may be yellow, white or black. Jadeite varies from white or near-colorless, through various shades of green (including an emerald green, termed 'imperial'), to lavender, yellow, orange, brown and black. Rarely it may be blue. Both of these names refer to their use as gemstones, and each has a mineralogically more specific name. Both nephrite and jadeite are mineral aggregates (rocks) rather than mineral species.
