Question: is nephrite the same as jade?
Answer: Nephrite is by far the more common form of jade. Nephrite ranges in color from mid to dark green or grey-green, but it can also be white, yellowish or reddish. Nephrite is slightly softer than jadeite -- nephrite is 6 to 6.5 on the Mohs scale, while jadeite is 6.5 to 7.
