Nephrite is a form of jade, a mineral valued for its green color and durability. It is composed mainly of calcium and magnesium silicate, and belongs to the amphibole group, specifically to the actinolite family. Nephrite is known for its hardness and strength, which is why it was widely used in prehistoric tooling. Its color can vary from white to dark green depending on the amount of iron present in its structure. Nephrite is usually opaque to translucent, with a glassy to silky sheen. It generally forms in metamorphic and sedimentary environments. Nephrite is mainly mined in China, Russia, New Zealand and Canada.
