Jadeite is a pyroxene mineral with composition NaAlSi₂O₆. Jadeite is found only in metamorphic rocks that form under high pressure and relatively low temperature conditions. Associated minerals include: glaucophane, muscovite, lawsonite, aragonite, and quartz. Jadeite color ranges from white through pale apple green to deep jade green. The pyroxenes are a group of important rock-forming silicate minerals found in many igneous and metamorphic rocks. ... Metamorphic rock is the result of the transformation of a pre-existing rock type, the protolith, in a process called metamorphism, which means change in form (from the Greek words meta, change, and morphe, form).
