Nephrite is a tough, fibrous silicate mineral that makes up one of the two distinct gemstone varieties traditionally recognized as jade. Chemically a calcium magnesium iron silicate belonging to the amphibole mineral group, nephrite is composed of an interlocking matrix of microcrystalline fibers. It is this unique, tightly woven felt-like structure that gives nephrite an unparalleled toughness, making it far more resistant to fracturing and chipping than diamond, despite its moderate rating of 6 to 6.5 on the Mohs hardness scale. While famously prized in a deep, glossy spinach-green color caused by iron impurities, nephrite also naturally occurs in a wide spectrum of shades, including creamy "mutton-fat" white, translucent yellow, gray, and even deep pitch black. Culturally, nephrite holds a monumental legacy spanning thousands of years, serving as the sacred "Stone of Heaven" in ancient China, where it was meticulously carved into intricate ceremonial axes, royal burial suits, and exquisite jewelry centuries before the second variety of jade—jadeite—was introduced to the region.
