It is especially prized throughout Chinese and Latin American cultures, often holding more value than gold. The term 'jade' was derived from 'Piedra de Ijada', a Spanish phrase meaning 'stone for the pain in the side' because Spanish explorers saw natives of Central America holding pieces of jade to their sides, believing that it could cure ills. The name 'nephrite' was derived from the Greek word for 'kidney', which refers to its supposed ability to cure kidney disease. Nephrite is one of two distinct mineral forms classified as jade (the other is jadeite) and up until 1863, nephrite was believed to be one and the same as jadeite.。Nephrite is a fibrous aggregate variety of tremolite-actinolite, a basic calcium magnesium iron silicate, whereas jadeite is a pyroxene mineral. Nephrite is more common than jadeite and although it is slightly softer than jadeite, it is considered tougher due to its denser structure. Traditional Chinese jade typically refers to nephrite since there are no actual jadeite deposits located in China. Today, green nephrite is considered to be the most valuable nephrite, but translucent, white nephrite was considered the most valuable up until the introduction of fine Burmese 'imperial' jadeite jade during the 18th century.。Identifying the varieties of jade is often considered to be quite easy for most experts. Nephrite can frequently be distinguished from jadeite by its lower level of luster and translucency. Nephrite's luster is slightly more greasy to resinous, while jadeite's is more vitreous. Nephrite is softer than jadeite, and it may also be distinguished by its lower density (although it is more compact in structure, nephrite's specific gravity ranges from 2.90 to 3.03, while jadeite's ranges from 3.30 to 3.38). Other green gemstones can often be mistaken for nephrite jade, such as aventurine or serpentine, but serpentine is much softer and aventurine's texture and color are not as smooth. Emerald and chrysoprase are much harder than nephrite and their colors are different than those of jade.。------------------------------------------------------------------------------------------。
