Why did my jade turn color? Why did my jade turn black!

A couple of days ago when I was adding new jade bangle bracelets to the web sites, I took off my everyday jade bangle, the one I wear all the time and set it on a table to keep it safe.  I like to put all the jade bangles that get listed on the web site on my wrist(s) to make sure they "feel" good: comfortably as well as energetically.   I touch them often while I write a description, and make sure that any abnormalities are described.  A few hours later, I went to the table to put my jade bangle on, and had to look twice to make sure that was really my jade bangle.  The afternoon sun had come through for a couple of hours and warmed up the glass on the table as well as my jadeite bangle, and the jade bangle had become more green all over.  That's not good.  Jade should never be exposed to direct sunlight for any period of time.  Jade likes the conditions that are in the jade mines: dark, cool and moist.
When I shop at the jade markets in China, the shops that have the best quality jade are kept dark.  The cases the jade are in have lights that turn off between customers viewing.  If the weather is hot, they often have fans blowing on them.  And there are bowls of water in the glass cases to provide moisture.  One of the methods for adding more color to gemstones is exposing it to heat. 

I put my jade bangle on my wrist even though it felt warm, and amazingly I could still feel the coolness of the jade stone.  Grade A jadeite cools quickly.  It appeared more green for awhile, but it often appears more green as I'm wearing it especially when the weather is hot.  Also, when I'm doing tai chi, yoga, my jade looks more vibrant, and glows from the qi energy, but that's a natural happening.   You may notice in some of the descriptions that jade will look more pretty as you wear it, and that's because of your body qi energy.   One of the reasons jade is so popular for centuries in China is because of the jade relation to body qi, and how the jade qi helps to balance the body.  You might get your jade bangle "all qi'd up", take it off and put it in a drawer, then weeks later when you get it, you have to look twice because it does lose the "glow" of your body qi when it's not worn.

But, what does it mean when your jade turns black?  If you take care of your jade, and it's good quality and natural color, it won't turn black.  In fact, true black is not a jade color.  It might be charcoal color, or deep deep green that looks black, but when you hold it to the light you can see some green hues around the edges. That's a method to check to know if your "black" jade is genuine jadeite or Chinese jade.



Exposing jade to sunlight and heat for extended period of time may cause the color to change. If you put your jade bangle in a drawer for several months, and it gets warm and dry, the jade stone gets compromised.  Wearing jade in chlorine water, for cleaning or swimming, may also affect the color.  Some Chinese jade sellers take good jade and bury it in the ground for months to make it look "antique" because of the way the color changes.  

Jadeite that has been bleached with acid to remove undesirable poor color, then treated with polymer or other coloring may eventually turn black because the acid will destroy the
jade stone.  More often, the acid and color treated jade loses its color.  When I'm not sure jade that was sold to me is really natural color, I keep it in storage, under the proper conditions, for 5 years or more prior to listing, and if the color remained stable, then it's probably the natural jade that is it supposed to be. 

Chinese people and Chinese healers often believe that if  you are very ill and have disease, or if the person wearing the jade is an evil person, the "bad qi" of the body will cause the jade to change color.  I tend to believe that, because when I had an illness that required a very powerful medicine that made me miserable, my jade bangle didn't look as good as it usually does.

Sometimes when I question a person whose jade bangle got black, or changed color, I learn that they bought their jade in a Chinatown.  I have been to many Chinatowns all over the world, and it's very rare to find the jade bangles in a seller's shop kept in the proper conditions.  They are often kept on glass shelves under strong light, air conditioning making the air very dry to dry out the jade stone.  And they are often handled roughly, not individually cased in a box which means they get chips, scratches and get worn out before it's even sold. If you see the jade bangles kept in these kind of conditions in a Chinatown, don't expect the seller to really know about jade.  Just because a jade seller is Chinese doesn't mean they know "all about jade"!

So there could be many reasons why your jade turns color.  Find out how the jade was cared for and stored before you purchased it.  And although it's not easy to know the truth about your jade without a gemology testing, it could be something other than jade, or poorly color treated.

Buy from a trusted jade seller.  Our best jade bangle bracelets and other jade is listed on the Jade Heaven web site.  Most of it is vintage, mined prior to the year 2000.  It is stored in dark, cool and moist conditions.  And most of it has been purchase many years before it is actually listed, to make sure there is no color change.

If you do want natural "black" jade, especially jade bangle bracelets, our Chinese jade, and the carved "Dynasty" Chinese jade bangle bracelets on Ying Yu Jade are the best quality you can buy anywhere.

  1. Would this be the same on why a jade turns almost white/transparent?

  2. If it turns transparent, the jade probably was not natural color.

  3. My uncle sent a carved jade locket set in gold to his mother in 1941. He was stationed at Pearl Harbor. In 1992, the locket was in a major house fire. I retrieved it from the ashes. The jade is now black. Does this mean that the jade changed color, or that it was never really jade. It is still beautiful, but some of the gold edging melted.

  4. The fire probably damaged the jade. Jade should never be stored in a hot area and that fire was hot enough to melt some of the gold. The only way to know for sure if it's jade, jadeite or something else is testing by a gemologist. But if it's still beautiful you can enjoy it and cherish the memories and its history.

    1. Sorry to hear about the color change. Genuine and natural jade doesn't change color. But jade that has been bleached to remove undesirable color, then color is added, may fade and change color.

  6. My jade pendant is white with a little bit of green. After I wear it for a while the white turns green in some spots and the green already on it turns greener. Is this good?

  7. Jade is supposed to be stored in cool / cold temperatures to keep it in good condition. Body heat, qi energy, the warmth can cause a "glow" or perhaps bring out the beauty, but if it's a major change, it might be because of acid color treatment. If it feels good to you, and it seems "right" and not obvious then it might be part of the jade. If you want to know for sure, then get it tested by a GIA gemologist.

    I have a jade bangle...with the round case and the color I had it first was pale to light green and last year it went darker and last week...I checked it...the color went to greyish white and specs if greens...what happened to it if I may ask?it was kept the last time in a filling cabinet where I store my valuable papers and stuff but this year the weather here in Toronto was really called and it kinda was cool to touch my filling cabinet...did this affect the color somehow of the Jade bangle?

  9. You could wear it for a couple of days, and see if it comes to life with your body and qi energy. If it seems to be a permanent change, then it was probably color treated. The cheapest jadeite that is mined doesn't look very nice, color is strange but it is still jadeite. So jade carvers bleach the stone with acid to remove all color and make it translucent, then add color. If you really want to know for sure, the only way is get it tested by a gemologist.
