Mention jade, and most people think of a green stone, when in fact, jade comes in a variety of colors. In addition to the familiar rich green hues, antique jade may be white, lavender, yellow, brown, gray, or reddish-purple.
Another important thing to understand about jade is that there are two different types of jade stones: nephrite and jadeite. Both can be found in river beds, or mined at depths of ten to twenty feet, and both come in all colors, though nephrite’s colors are less vivid than the colors of jadeite. Hence, identifying the two stone types can be difficult.
