When I think of jade jewelry, I envision a translucent to opaque green stone. True jade can be either of two different minerals, jadeite or nephrite. Both variations of jade are tough stones that don't break or chip easily. All jade typically has a medium to high polish.
We see so much green jade that it's easy to forget the gemstone occurs in other colors.
Jadeite is the more rare of the two jade variations, and the most expensive. Most of the world's supply of fine jadeite comes from Burma, but deposits are found in Guatemala and a few other areas around the world.Jadeite occurs in many colors, including greens, white, lavender, yellows and oranges, black and reds.Evenly colored, translucent emerald green jadeite is called Imperial Jade.Jadeite ranks at about 7 on the Mohs scale, compared to 10 for a diamond, but jade is a tough mineral that resists chipping and breaking.
Nephrite is more plentiful than jadeite, and that makes it less expensive. The Xinjiang Province in China produced the jade traditionally used by Chinese artisans until Burmese jadeite became available to them in the 1700's. Nephrite deposits have been discovered all around the world, even in the United States.
Nephrite jade is found in fewer colors than jadeite.Instead of a bright emerald green, nephrite greens are often grayish or mottled.Nephrite ranks at about 6.5 on the Mohs scale. Because it is softer than jadeite, finished pieces cannot be as highly polished.
