Nephrite and Jadeite are the only two true Jade stones. Even though they are both very similar in appearance they are two very distinct stones with different composition and structure. Nephrite is the older of the two and dates back to ancient civilizations. Nephrite is also the most common form of Jade and can be detected by its low luster and low translucency. It is also typically the more affordable of these two Jade stones. Nephrite consists of magnesium and calcium and is typically found in shades of mid to dark green and white although there are other varying colors available. Ancient and traditional Chinese Jade is made from Nephrite.
Jadeite was introduced from Burma in the late 1800's and has become the more sought after of the two as it is much rarer, more valuable and is considered a precious gemstone. Jadeite is a silicate mineral with sodium and aluminum and also contains traces of chromium and pyroxene. Jadeite can be found in a wide variety of colors which includes green, lavender, pink, black, yellow, and white. The rarest type of Jadeite is called Imperial Jade and is the most valuable. Imperial Jade contains traces of chromium which gives it its rich emerald green color.
Nephrite deposits can be found in locations such as China, New Zealand, Russia, Guatemala, Canada and the US. Jadeite deposits are found in Burma and can also be found in other countries like Russia, Japan, Canada and the US. Jade is typically mined in large quantities with large blocks sold as is to buyers in Asia. Buyers bidding on a stone do not usually have the opportunity to see the quality of the Jade until after the sale. There is usually a risk involved as to whether or not the buyer is getting a high quality stone.
What Are Your Favorite Jade Colors?
Whew - what a comprehensive article on jade! I love the emerald jade especially in the jewelry. I couldn't help noticing that the jade sculpture of dragon looks so impressive.
I never knew that there was a lavender jade. Very pretty, although I think I still favor the more traditional green tones.
Awesome post on jade -- my favorite is green
It's beginning to sound like there's an echo in here, but I'm adding my voice too: I didn't know there were so many jade colours! I thought there was only green!
I've always loved jade. Nice variety here.
The light green is so beautiful, love the dragon... Thanks for shearing.
Didn't know about all these jade colors. Interesting and informative article.
I love jade - don't have any though :(
I knew jade is found in colors other than green, but didn't know there were so many! It is a lovely stone.
The Chinese tend to like green jade. You can also find many Buddha and Goddess Of Mercy jade pendants which supposedly can help ward off evil spirits.
